350 hp

Look around...average price for a set of cams for the 4 valve is 11-1200 dollars. And porting and polishing is a VERY difficult thing to do (lots of time and money involved).

You Could Be right but I thought I swore I seen some between 3-like the 600 range

i have seen them for like 600, a piece for crazy custom grinds.






anyways, what kinda power could i expect to see with a still streetable cam but giving me the most bang i could get. especially one that likes to go to the 7k+ mark.

Your knowledge of cars is obviously not up to par if you think our engines can handle nitrous any better than a 4 cylinder. Obviously ours can take more of it, due to more hp stock, but a 4 cylinder can handle its share just fine.

i saw first hand a 4 cylinder blowing his motor while using NOS. and let me tell you i was laughing my ass off. that is why i said what i said.
 
Mike, iv been looking arround for them vt stage 1 cams, but all i seem to find are 2v versions. Would i just buy 2 of them if thats what i wanted?

How much of a diff are the stage 2's?
 
ok, i found some at modmax.com i dont know if they are stage 1 or w/e but they list them as

ModMax 370-25200 4.6 & 5.4 DOHC N/A Mild Street Strip

(I) 205@.050 .460
(E) 205@.050 .475





ModMax 370-25202 4.6 & 5.4 DOHC N/A Hi-Perf. Street and Racing

(I) 224@.050 .460
(E) 224@.050 .475



what do those #'s mean to me?
 
Those are cam specs. They show intake and exhaust duration and lift. Also, someone mentioned the 5.0 Cammer. First it's not making 550hp NA. Second your Chevelle 350 was not making 500hp NA. And last, the cammer is not a stroked 4.6!

BTW, you can make 350hp NA at the flywheel with all bolt ons, headers and Cobra intake. No internal engine work required. :Beer

i mean i know that those are specs, but what does that translate into real world power increases?
 
So, full exhaust+ headers, cobra intake, cams, and all them bolt ons that lms has...what kinda power should i be looking at?
 
I would guess 350-375 flywheel horsepower with bolt ons, stage 1 cams, headers and cobra intake.

That is Stage I...

and stage two would offer what diffrence....i know the diffrence in the specs, but what does it offer
 
Stage II and III are known as hi-po or blower cams. If you have a 5.0 stroker, you'd use Stage II cams because you need a more aggressive profile to feed air to the engine and spew exhaust out faster. Ususally, Stage II has a "lopey" idle, meaning it seems as though the idle is hesitating. Stage II cams on a stock Mark VIII would hurt performance, especially on the low-end. Probably a 15-30 hp gain, depending upon the heads and intake.

Stage III you use for boosted applications. The profile allows more dense air from the supercharger into the engine. Probably a 20-50 hp gain, depending on the profile and what your blower's psi is...
 
I allways thought Headers were the number one performance boost for the buck, but I guess that depends how efficent the factory manifolds are.
Can anybody explain the differance between Long/Short tube headers, (other than Torque range)??
 
stock intake?

What about using all bolt on's (cold air, wires, coils, exhaust w/ headers) but using the stock Gen 1 intake? What kind of HP numbers would u expect then?

He was using too big a shot on a completely stocker probably. Cuz I have seen the turbo Laser and Talons of 'old' (early-mid 90's) running 11's out in Osceola for a long time wit NOS.
Modified a bit, but they have been out here for years...........same cars. Just depends if you follow the rules or try to skirt them with too much. Alot of them 4 cylinder Turbo cars are very fast and you won't want to run into one IE: Subaru STI, and the Lancer Evolution lately. Low 13's out of the box. They run right beside the new GTO LS1's. ( I respect speed, not what brand it is or what size the engine is)
 
damn this is an old thread....Mabey were all feeling retro...MABEY i should bring up the LS1 thread again, cuz i know yall loved that one soooo much.
 
The only cost effective way to do this is by installing a factory Cobra motor like our friend in a neighboring thread. You could probably even find a blown one in a junkyard and just swap the top end in....
 
how limiting is the stock gen 1 intake?
