I put long tube headers, full dual exhaust, knn cai, egr block off, 510 lift cam, ported heads/intake/throttle body, 1.6 roller rockers, valve springs lifters, 15000thdegree mill on heads, just curious as to what ill be pushing horse power wise..will tune an dyno once finished.

automatic or manual, these things make big difference from what i hear, more cam info would help to, but id say probably 350ish give or take but then again im retarded

Who ported the heads? and what level of porting if it was AI or Le.. etc. That makes a big difference

94z28shane

Idk the exact numbers on the porting, the cam is a hair pin smaller than the lt4 hot cam, and its an automatic

Howards cam 510/500 110 lobe seperation. Proform 1.6 chomolly roller rockers, the port is gasket matched all around, k&n cold air intake, b&m stage 2 shift kit, full smog and egr block off and delete, pacesetter long tube headers with two flowmaster tens with turn downs, stock 273 hwy gear, 58mm throttle body with air foil, valve springs and ls7 lifters. Thats a little better description.

Probably 330whp. Many questionable components there aren't helping your horsepower cause much.

94z28shane

Hmm whar components are those

The Howards cams are unpopular in an LT1, especially when there are dozens of other PROVEN performers for the same price.

Proform rockers are a risk. They're the cheapest Chinese rockers you can get. Failures are pretty common.

Gasket-matching is a HUGE no-no. You create port turbulence by expanding the port shape then contracting it. Bad for power and port velocity.

Stock 2.73s and that cam will be a dog. It'll be even worse with the stock converter.

A 58mm throttle body is completely overkill and a waste of $, unfortunately. A stock TB will support your HP level and then some, without the idle quality issues common with aftermarket throttle bodies.

Other than that, everything else looks good.

i say >325 to wheels. My 355 with ported heads and 503 made 353/369 after dyno tune.

stop trying to mod the car so cluelessly, you have done more wrong than right.

What's the duration on the cam? I'd say 325rwhp with the converter unlocked. Given the info you gave us..

id say the same 325 -330 range ,that gear is gotta go ,you should have done a little more research before you start throwing parts together and money at it .
