How much horsepower should i expect to gain form an lt4 hot cam with stock rocker arms?
If thats all you have done to your car, I wouldn't expect a whole lot of improvement. IMO I wouldn't pay for one, I would get ahold of BRet Bauer and see what he can do for you with a custom grind
i have 100 wet shot,headers,y pipe, 3" cutout, borla exhaust, no egr, air pump, cats, maf ported, ngk tr55s, 8mm plug wires, electric water pump, computer tuned, 160 thermostat, new opti, etc
Why on earth would you want to go through with a cam change and not go to roller rockers? If you cant afford the rockers then you cant afford to do a cam swap.
i never said i was, i just want to know haow big of a difference it would make
and by the way I already have the cam, springs, etc. I just wanted to know if roller rockers were necessary
You would notice some difference, but there are alot better cam out there than the LT4 with alot better power gains.... Like the CC305 or CC306...
What lift are your springs good too?
If he has the LT4 springs they are only good to .525" lift, which there is no way the 306 can live with those springs probabaly not even the 305 can get away with it. Personally the LT4 cam isnt worth the trouble to do a cam swap unless you are budget restricted or emissions. Also the lift isn't that high on the LT4 cam to begin with and if you dont or cant upgrade to 1.6 rollers then you loose that much more lift and improvement
Agreed.. Thats why i asked what his lift on springs where good too. He did really say weather they where LT4 springs or not.. But since he alreadys has the Cam, and the springs he might as well just toss them in.. With or without the RR's, does really matter.. Either way.
When I bought my Z it had the LT4 hot cam in it. Couldn't tell a diff. over a stock Z. It just hit a small lick. for the trouble, I'd spend my money else where or keep saveing. If you do the ECU will need a tune.
