Flying you still out here thought you had sold the engine.....
If you do remember I offered a solid roller and lifters to help see if you could get a 8 and one of the closest to your Dyno number. FRH ls3 stage 1 Brethren. Remember me now? Don't go below .700 all the guy's listed can do work. I'm a MJ fan. Mike Jones.... He's pretty good at getting you close to the time you want. Mr. Straub is damn good also he's the Morel lifter's head guy. Add some RPM as I said last time and if you've gotten that Vacuum pump now have at it. The world is for the Taking. You can make more HP at the same RPM with the solid roller but more *RPM .....helps with the ET... if gear correctly.
I also see you picked up around 13 hp from the last time 707-708 to 720. Nice!

I’m talking to ER racing about a camshaft also. Him and I seem to be on the same page. Looking to peak power at 78-8000 and go 85-8600 on the shift.

Here's what Mike Jones Spec'ed me and the Rowdy Yates heads the RPM is off by just a TAD bit 275 would be perfect. Me and Darth came up with this for 800+ @ 13 to1 Compression and the idea of a 8 second pass with my 408. You can have it. I'll still get the same one. Run it by Eric and see if he likes it and tell him I still thank him about the rocker arms.... 1 of my Favorite Mentors!
Cam# LS1, R82448-86436-115
277/292 @.050"
.448"/.436" Lobe Lift
.785"/.763" Net Valve Lift (after Lash)
115 LSA
Price: $529.83
---
That 260 cam I got for the Ls3 heads is at 260/272 with a 113 LSA which is good for around 7500 peak with lower comp. @ 11.8 so... about 750 ish at the crank.
I told you this before:
Just get the 8 second Pass!!!!!!!! That would hurt all Known. With Factory Ls3 heads. And a real car. LMAO! Who's winning? The Factory!

I thought you and Darth were the same guy?!? LMAO
Not sure if that’ll even fit LOL. Need to make it fit within the confines of my current short block.
227/292 is pretty large!!

8000 is a lot and you need RPM Mike can take some of the lift out. It's good too about 8700 peak. And or about a 7k stall. Based it off the guy with the older build with a 408 15 to 1 comp engine. Car was around 3200 lbs with a 275 cam and peaked at 8500.

Older build's in my book.. both small bore's to give us a base as to what a 4 inch crank and @ .050 duration gives us. I don't do all that crappy tech mumbo jumbo, base the RPM and crank with a known duration at .050. You can fool it to think it has more RPM with more LSA...wink wink... a 266 cam with a 118 LSA. You get what I'm saying? We know a known RPM base with a given duration @ .050. Here's the guy from SAM and Dwill73 from YB. To give you a general idea or Ballpark #.
Super Victor Intake Manifold. GCRE Stage 3 Port Work
4500 dominator flange, extensive plenum and runner work.
and the Camshaft is a comp cams, HXL lobe 274/288 @ .050 .810/.817 lift on a 115LSA
this was on a 408 that was 14.8:1 compression it made 675rwhp through a th400 5800 converter 9" with 40spline gun drilled axles 4.56 gears and a set of slicks.
the converter was not right in the car it needed to be around 6800 and it would have gone faster but going through the traps in high gear at 7100rpm it went 5.87 @ 117.20 with a 1.29 60ft in a 3200lb race weight car
we turned it 8500rpm

Started on a Superflow and finished on a DTS dyno. According the Superflow the DTS is 5% lower. Between time constraints and a **** load of problems is the reason why I had to finish on a DTS. Had to break up the dyno sessions in two days, because of work schedule. First was on a Thursday it made 821 @ 7800, 621tq @ 6100.

Yea mine is just a street truck. Like to see 550-600 hydraulic will do fine for me. I was just curious on his workmanship. I am lost when it comes to cams. Just want to be able to tell someone what I have and what my goals are let them do the thinking. Mainly needing a place to start I guess.

What engine and how big is it and i can place you in the ballpark. Just walked in from hitting another lick with my boy's they buy lots and build houses..... Let me roll up 1 and see what you got J just brought back some good from Colorado.

550 to 600 at the crank or rear? If you've got a 4 inch crank this will be EASY! If not still EASY! 238 @ .050 will get you close either way for both. Put it out there and we can see it may need less or more. But I do know this a Ls3 as is with ported heads and a Hyd roller put down 530 rwhp thru a manual trans.... nothing special.

It’s a 6.2L l92, stock crank, 6.125 rods, wiseco -3.2cc pistons. No charger at the moment. I will be buying pushrods, new valves and trunion kit as well for rockers. Just to give you an idea. It’s in a Sierra Denali truck.

You say charger are you talking super..... but that doesn't matter let me finish rolling and take a puff and think about it ......I already got you but let me enjoy this puff. Oh yea whats the Compression I'm working with to start off with?

Also crank or RWHP. The REALIST MF you'll ever meet. I don't waste my time for a lie or something i don't know. I'll do a reference for when you ready to Buy parts. I can give you a Ball park # for a cam......between 250- 290 for example.
