Engine, Part Deux

Since the decision was made to rebuild the engine, why not go with a little more power? The 1991 Vette L98 engine was rated at 240 HP. Not bad for 1991, but at the late edge of the 20th century, the stock Corvette was now putting out over 300 HP! Time moves on, and quickly, eh?

The short version of the story is that it took 18 months and about $5k in parts and labor, but instead of 240 HP, projected HP should be somewhere north of 350 HP, south of 400. Dyno time is definitely part of the plan for 2007.

18 months? To build a Chevy motor?? I know all my car guy brethren are wondering why it should take so long to build a garden variety SBC powerplant. Fact of the matter is, the guy doing the work (Pete at Pete’s Machine Shop) is a perfectionist! He is meticulous, very good at what he does, and sets his tools up to do not just one, but several customer orders at a time. He also works on his own and is in high demand. I will definitely use him again on the next project when the time comes.

The other side of it is that I could afford to let the engine build take 18 months! During that time I was saving up for the engine build and working on other parts of the car. I paid off the engine guy over time while I removed/cleaned/replaced/modified/mutilated other parts of the car.

The other main player in the buildup was TPIS from Chaska, MN. These guys are very knowledgeable about modern day injected Chevy engines. As a result of their influence, I updated the engine with one of their Mini Ram intakes, a ZZ409 camshaft, and a Level V chip for the engine computer.

Overall, the engine build isn’t too radical. Just a standard balance and blueprint, .030” overbore, 2.02/1.60” valves, intake/heads port matched, etc……

......but will it all fit?

 

Looks like there is hope!
