Project C4, 85 Corvette

[Steve85]

I will start with where things are now and update with new and old stuff. These cars are excellent platforms with a lot of aftermarket support.

Here is the engine in the car, ready for tuning. There is no filter on it because it does not fit under the hood and I wanted to be able to close the hood for travel today.





The last issue to be resolved for fitting the 18* heads in place of the standard 23* heads was header fitment. These heads put the exhaust mount a little higher, wider in the bay and the center outlets are spread wider. I found a shop in H'burg JL Maintenance where they build hot rods to make the mods at $45/hr. (AR fab in winchester wouldn't do it and charges $95/hr anyway)

First they cut off the flanges, split the center tubes, then tacked on the new flanges for a test fit.



After several test fits there was a huge gap that needed to be filled and the thin metal split so some additional rod was needed to seal things up. The welds look pretty good given the situation. He was building a pro-stock chassis with beautiful welds..they guy is good.



After getting everything hooked up, I started it and had no oil pressure. I left several holes used for cross drilling the cam journals open (I was told with roller bearings not to worry about these, wrong.

So the intake came back off this week, the holes were plugged, I installed a dummy pulley in place of the AC unit to retain the stock belt and it runs OK now with some tuning needed, of course.

The new wheels are from a ZR1 owner (a 600+HP 415cid by Lingenfelter) and are CCW Classics. Front are 18x9.5, rear are 18x12.5 They stick out a little but I have flares from the 96 Grand Sports for the rear fenders.



That's a long post, but like I said,  I have done a ton of work, even in the last week. I will find the pics of my interior resto, C5 brake upgrade and paint work. to follow-up.
