Default L98 engine rebuild in progress.



After a year of planning, decisions (thank you, TPIS), and collecting parts, the horsepower project is almost done. I thought it was ridiculous that my '87 Corvette C4 350 cid engine made less than 300 horsepower. The parts are a SuperRam intake, Air Flow Research 195cc SBC Street Port Aluminum Heads, ZZ409 Hydraulic Roller Camshaft .520" lift, 226 single duration pattern, and exhaust headers. We will see what is generated when I get it on a chassis dyno in the spring at TPIS. Engine photos by Alex.

"In the truck" you also say? Here's my 10.1 L V16 Sierra. I'm hoping to up the displacement to 10.5 L later this week.

I picked it up earlier than expected. Here's my new 10.5 L Sierra Z06. I don't know why the PO painted one valve cover gold, but that's an easy fix.

I had to digest your "In the truck, you say" comment, but when I 'got it', I . Well played, sir.

1970 LS5 454 11 years after being restored.
Not too bad, no leaks.
A little detailing and it will look really good.

Not finished yet, but here are pictures now with the body back on the car.
Please excuse the dust because I just received the car back from the painter.
