Somone just answer his question, there is no reason to ban for asking a question about LSx or BBC...

First off, no, it doesn't.

That's PROBABLY why he asked the question "What combo of parts, cam, rollers, springs, heads, cr, etc....?"

And I bet if you told some old school guy that STOCK small block heads are flowing 350+cfm these days, he'd call that "pie in the sky", too. He asked a question, he deserves an answer. Keep "your beef" out of it UNLESS it gets strayed away from the original question would be my advice, but I'm not The Modinator 3000 like you.

Do I need to copy and paste every time a mod has typed "use the search function" in somebody's thread? Now you're saying new threads push other threads to the bottom of the stack?

Come on dude, he asked a question, you jumped his **** FIRST POST without him ever getting a response.

Do not use the canted valve heads on anything remotely a street car. There LS7 or 265 heads will be more than enough flow and keep the cam under 700 or even 650 if want it to last more than a couple weeks with out a rebuild.

There are 2 problems with the build that I see... #1 800+ lift will kill a set of valvesprings in less then a season of racing, nevermind driving on the street. The sustained running times of a street driven car are going to kill the springs so fast it's not even funny. #2, if the canted valve head is really needed, the compression has got to be in the 13 to 1 + range, or the motor is gonna have to be built to turn 8500+, and in order to do that the intake and cam will lend itself to be a cranky **** to drive around unless the car has a 5000+ converter and some steep gears, like 4.56 or so, again killing the streetablilty.

can you do it.....I guess, but why you would want such a cranky car to drive and the huge amounts of maintenance I have no idea.

fwiw one of my better firends has been running a big block in his old mustang for years, he originally built a motor with 14 to 1 compression and 800 lift.... after about 8 sets of valvesprings, redoing the heads twice, and enough $ in race gas to buy another car... he pulled the heads and put a streetable compression set on along with a streetable 600 lift cam. Car lost nearly 200 hp, but now he can drive it and enjoy it.

You build an lsx like you are talking about/planning, and I see you doing the same thing in a very short period of time. Motors like that, with those kinds of parts are race setups, no way around that.

Apparently, you haven't figured out that I do not build engines, I don't know about this stuff. I'm a commercial jet pilot, thats what I know.

Yeah, and I've learned alot in 5 years. Solid roller cams and huge lift is not something I've ever concerned myself with till now.

In a year or two, running .800 and .900 on the street without issues may be commonplace, this is how fast this industry changes. I wish I could remember the ********* back in 2001 that told me Agostino couldn't build a ~500 RWHP 436ci. Sure it did a tad less but they basically shut up all the cheezdicks that said it couldn't come close. Now 500 RWHP is crap.
Think ahead, push the limits, it'll help this industry.

I still dont get why more people arent running All Pro heads by top porters. I have seen two sets here locally that flow stupid amounts of air. I mean real flow bench numbers that kill everything else I have seen advertised.

That kinda lift will never not be an issue for most guys. For a stock gm head it is VERY difficult given the size spring pocket you have to work with. I cant speak to the aftermarket companies, but the traditional LS style, not C5R or LS7, also have the same problems.

I sure why not, that is if you own stock in a major valve spring manufacture.

Without the fear of being banned... and being a bolt on only mod type car person...

what is the stock OEM lift rate?

Quickin

Wish I could buy everyone a stroker engine.

A friend of mine is getting my 436ci, he's a member here "1999TransamWs6". He lives near me and has helped me with my car a few times over the last couple years when I was in a spot. He came to my house and pulled my heads off for me when I needed to have them rebuilt. Saved me alot of hassle and $$$. I've been waiting for alot of $$$ and that time is here. I told him he could have it when my new engine is built. I'm even gonna have my builder completely refresh it first, like new, or I'll have it rebuilt to his specs. Everything is just about money.

You ready for a 436 Joe?

I'll be running a Set of WCCH LSW's On my race motor, I'm looking into .900 lift but it won't be driven on the street.

.900 lift springs with 320+ seat and close to 1k open will take a toll on every part of the valve train. I would be leery of putting too many miles on the car

In the wake of how this thread is going, I'm cracking up at this post being so gently squeazed in here, thats great!!!!

4 pages in a matter of minutes, thats cool.

Hey, I think I'll consider other options as I've learned something.....noone is doing this on the street with "success". My question has been answered.

Thanks everyone.

It a simple question of durability. Nothing more, nothing less. CAN it be done? Sure. Should you do it? No. Your builder is recommending you don't go down that road (pun intended) for a good reason.

I'm leaning towards this thread being more about bantering a more or less "common sense" question, but there's nothing wrong in my eyes with posing some "what if" threads every once in a while. The key phrase here though, is once in a while

If you consider "success" changing valvesprings every couple of trips to the store and replacing valveseats and redoing the valvejob more than occasionally then by all means, go for it.

I run Comp 948's @ 340# on the seat so I have some experience with it.

I'm on my second set of 948's and the heads have been sent in to TEA once for new seats and a valvejob...

A couple of years ago I ran a bbc with a .775 lift cam on the weekends 30 or 40 street miles each time. Never lost lost a spring over the year I drove it on the street but it did start leaving a fairly deep wear pattern on the camshafts lobes.

Currently, I just lost a roller lifter on my TT 421 with a 750 lift on the intake side cam. Its more strip then street, but I like to go for a short drive every so often . And yes, it is starting to show a pretty good wear pattern on the intake lobes. It's all new old NASCAR stuff so you would think it could handle it since these things can go wide open during a 500 mile race. fortunatley I caught it at idle and it caused very little damage.

Going for a smaller cam this time around since I would like it to be more street and less strip in the future. From personal experience I would vote no on the larger lift cams on the street.

In my experience i would say that 750 would be your limit to anything streetable but you will have to keep a close eye on valve adjustments and make sure you check them at operating temp because of how much the block and heads will grow from cold to hot. Also i have a friend that has around an 850 lift cam in his racecar that if it is cold outside (say 40 deg.) his car runs extremly rough for a few minutes because the block shrinks so much and closes the valve lash up.

also if you are just looking to make crazy hp's you could make plenty with the right setup around .700 and it would be alot less stressful on valvetrain

austin21

before mr. *** clown comes back with all of his nonsense and bans you for not knowing this i believe it is .585 on a 116 lsa but just to make sure i would ask someone else or just do a search you should be able to find it somewhere...and imo i think pat needs some cranberry juice
