The LS1 puts out 345HP at the crank. The Hooker headers are more a midlength header, just a little longer than a shortie from the looks of it. A Flowmaster is not going to net 15HP.

The LS1 puts out 345HP at the crank, LS6 is 405HP in the Vette and 400HP in the CTS-V (don't know where the other 5HP went?). A flowmaster is not going to net 15HP, neither is a K/N going to give 7-10HP.

Car Craft, December 2004, page 41. Quote: Our testing reveled the GMPP LS1 crate engine makes more than the 345 hp claim. As the numbers below indicate, this is a 400hp motor right out of the box. Unquote The 315, and 325 hp claims are for the SS, Z28 and Firebird. The motor that Car Craft tested was bone stock right down to the exhaust manifolds it made 402 hp at 5700 rpm and 398 ft pounds of torque at 4300. All the testing was done on a engine dyno.

And like I said a couple thread up I am stating flywheel hp. Of course a Flowmaster wont give you 15 rwhp but I bet it will give you 15 FLYWHEEL HP.

I still consider the Hooker Headers a shortie, just because it looks a little longer doesnt mean its a mid length, you can tell the difference between the two plain as day the collecter is larger and located farther away. If it bolts up to the stock location its a shortie. Anyway who Gives a F*ck, this kid has none of it anyway.

i've seen a few gen III small blocks in colorado's already. not exactly complicated by any means even if he had done it.

on the other hand, i know a guy who'd brother's cousin's buddy's dad's friend put in a set of vinyl floor mats worth 55hp. between that and a set of side pipe's that's all he'd need. not sure where you'd find a 300hp 5.7 other than a y-body LT1. if i recall the lowest rated gen III 5.7 was 305hp. some people can't even B.S. correctly.

We should come together as a forum and, instead of rediculing this kid, try to find him some friends...

HAHAHA!

What a brick!

Anyone remember this horrible movie on the USA network/channel a long while back... It was one of those rainy Sunday afternoon movies. Some lady was a (short) bus driver... Her motor went, and the local garage only had a "race car" engine to drop in. She ended up getting terrorized by some black car, and they were all racing around like the dukes of hazard.

Anyway.
