after this question

first and foremost, I have been making a few threads here and thre, sorry but Im so undecided as to what I should do.

I also need reccomendations on what gearing to get, along with what cam to get.

firstly, how difficult is it going to be to do a head/cam package, I understand my headers, intake manifold, etc will ned to come off. But this may be a dumb question, but will I need to drop my engine to do a head and cam package install?

I am looking for something as streetable with a 224/224 or a 228/228 cam, but want a higher peak HP. I was thinking something in the 230 range, but not as big as a 238. I will have a

If I go with 3.73s I was thinking a 230 cam with 112 LSA or with 3.90 gears 236 cam with 111 LSA... I think those would be somewhat streetable.

Also if the head and cam package is that hard to do ( dropping the engine) then am I better off rebuilding to a 383 and going with even a bigger cam?

I was looking to spend 2 grand, but if the rebuilding is a better idea I am willing to wait a few more months and spnd 6 grand. or even better yet wait a year and spend 12 grand o a new L92 block... inwhich that case what would be a good streetable cam?

I doubt this will get many answers since I have so many minor questions and its basically all preference, but I dont wanna make a mistake.


----------------------------------------------------------

Some key points

I have all supporting mods: Lts, ory ( soon tsp true duals) and Lm1/dynomax bullet, lid and cold air induction ( havent ported T/b or MAf yet) also no tune yet.
engine has 85,000 miles +/- a few
a 2002 Z28, pewter, m6
currently rebuilding my transmission
aluminum flywheel
and ls7 clutch
going with anywhere from 3.56 - 3.90 gear range, FOrd 9" probably a Moser, leaning towards tru trac. also have almosta full suspension on the car.

if easy to do, going for my stock 346, with some ls6 heads and a 232 cam(example)

if not an easy task, may wait a few more months and do a 383 with a bigger cam.

or if that isnt worth it, I will wait over a year ( dont really wanna wait this long at all) and do a l92 with, yet even a bigger cam

looking for somewhat streetable, a daily driver, but due to the lack of low end, that is why I am choosing 3.90s, but if a 232 will be reasonable I will stick to 3.73s or 3.56s.

If anyone can help , please.

to help make myself a bit more clear ( hopefull, that is my goal) I will provide a couple of examples of what I am wanting to do...

I am thinking of doing a head/cam package first. Even if it will take a lot of work...A cam in the range of 232 - 236 duration 112 or 111 LSA for a bit higher RPM torque than stock with 3.73s trutrac....

3.73s because in over a year I will leave my drivetrain, aluminum flywheel, 3.73 trutrac moser and aluminum 1200 Hp rated driveshaft..but upgrade my powerplant to a L92 and go with a larger cam. the 3.73s should pull just fine, even if I go with a rather large cam, since It has a 4.0 stroke it will make plenty of low end torque, but I cant have any overlap past 110 LSA, since the stroker will not be a good choice with it.

what cam would be good for a DD, makes a lot of torque, but high Horsepower, so I want midrange and top end, but dont want to completely lose power during cruising..

Also I drag race and Track race my car, besides it being a DD.

A head and cam swap is not very difficult, with help from a friend it should only take a weekend to do all saturday and sunday.

Going with a built engine is always a good thing IMO, so if you have the $$ to do it then do everything at once. if you dont have enough right now for the engine but you can get the heads/cam then go for it.

I suggest you at least buy a ported TB and a LS6 intake for the swap too.

I have a 232/236 cam and it is completely street friendly especially since I have a higher compression motor. Heres my graph so you can see how much power a cam like this can make and where it makes power at, made lots of torque in the low RPM's.

sounds good.

In that case Id want to do a head and cam package with my 85,000 mile engine an dby the time I hit 100K - 110 K, I will get a brand new engine as well as rebuild my LS1 and save it as a spare.

What gears are you running with your cam an dhow much a difference did you see after the cam change? what heads are you running?

also I already have a LS6 intake ( its a 2002)

brad8266

iTrader: (23)

Stock 3.42 gears, i did a forged engine/heads/cam all at the same time so i dont know how much the cam was worth. TEA stage 3 heads.

LSGunZ28

iTrader: (8)

So I should be fine if I go with 3.73s...

would a stage ls6 head work well, or should I go with what you had?

LSGunZ28

iTrader: (8)

bump!

brad8266

iTrader: (23)

3.73 will work fine, and a worked LS6 set of heads would do good.

So Brad, lets say I get a 232/236 cam or a cam of similar characteristics...as well as a set of LS6 heads, along with new pushrods, springs, lifters, retainers, etc.... That being said

with a Ford 9", aluminum driveshaft, Aluminum flywheel, all boltons, inluding a 25% u/d pulley, LTs, trueduals ( soon to have) but LM1 for now and no cats, and a lid. also a tune.. I should be seeing similar numbers as you? perhaps a bit lower, since I am not sure how high your CR is..

Im probably gonna get them from Texas Speed.

iTrader: (8)

where did you get that cam from and what are all your boltons if you please?

Im looking for these 2 cams similar to the one you listed, what LSA are you running @?

mods in the sig, i still have to install my ported TB, and underdrive pulley, power was made through z06 wheels, and 12bolt w/ 3.73s

u cant go wrong w/ either cam, call TSP up they'll point u in the right direction

brad8266

I cant say exactly how much power you will make, all setups are different. My heads are 57cc, compression is in the 11.8 area. If you go wioth a 9" it will eat a little of your power, just a few HP.

brad8266

iTrader: (23)

Its a comp grind on an XE lobe. Mines a 112 LSA.

I like the 233/239 and the TQV3, both good cams.

what kind of flywheel do you have a steel? also what driveshaft?

also can you link me to those heads? chat CR would they leave you at?

so 406 RWHP with all boltons excluding a ported TB and underdrive pulley as well as a 12 bolt with 3.73s

Also what dynamometer was it dynoed on?

thanks.

LSGunZ28

iTrader: (8)

thanks for the input..

but what bolt ons do you have?!?! , I didnt see if you ever mentioned them...

brad8266

iTrader: (23)

pacesetter headers, custom out the back duals, unported FAST 90, Nick Williams 90mm TB, March ud pulley, slp lid, MAfless, 42lb injectors, walbro fuel pump. I may be missing one or 2 but thats pretty much it. I have about all boltons except an electric water pump and cutouts.

LSGunZ28

iTrader: (8)

cool thanks a lot

so you are on a steel flywheel? and a stock 10 bolt?

LSGunZ28

iTrader: (8)

cool thanks a lot.

so you are on a steel flywheel and a stock 10 bolt?

brad8266

iTrader: (23)

yeah i use a SPEC billet stell flywheel and a stock 10 bolt.
