Nope 85 riviera was RWD. Lots of fabrication to make it work.

I run the 1/8 in 9.0xx in my 93 SSEi. That'* going to cost you dearly to do the same in a Riviera. The Riv is actually heavier than my SSEi.

But:

You will almost certainly never really improve the UPPER end of a Series 1 L67. I would take your first $1000 and invest in a beater for the winter. Then start buying your extra parts. LIM, SC, Heads, cam, rockers, springs, lifters, etc. When you have it all, take your car down for however long it takes. As you work on it over the winter, save your $2k for the trans so when the car is done in the spring, you can go get the trans done.

cool. i just removed my headers and cross over pipe and welded the cracks and welded the pipes to the flange. then used grinder and smoothed out the ridge on the inside of the pipes. i then coated them in VHT flame proof ceramic paint. 1300-2000 degree paint. i will add pictures soon

They're not headers. They are exhaust manifolds. Porting them with stock heads is of no value. The stock exhaust ports in the heads are already smaller than the inside restriction of the OEM weld from the flange to the runners.

VHT hi-temp paint won't last or do you any good. Your manifolds will cook it off. You need to use the same coating I use.

Here is the one I just ordered. A few others use it on here, and I suggest you do too. BTW, you most likely will only need the small can.

this paint is some i had left over from my mustang. it hasnt baked off my mustang yet and its been on there 4 months. i cant figure out how to upload pictures

Your mustang doesn't have hot manifolds like an L67. Now you'll have to strip that crap off there before you can do anything else with them.

There is no insualiting benefit at all to that paint. You need to ceramic coat them to increase exhaust velocity. I suggest pulling them off, stripping them, and getting it right.

i have decided to rebuild my transmission and pick up a supercharged block with heads and rebuild it also. where can i get a set of 20 over forged pistons. i want to get 8.5:1 compression with the stock heads.

also. i removed the check valve on my transmission modulator valve and blew throught both sides of it. should i be able to blow throught both ways or just one way?

You are already 8.5:1 compression. What did you think it was?

That checkvalve isn't even really necessary. I have one on the green car, but not on the green car. I think. I'd have to check.

wasnt that FWD. transverse 307 olds eng.?

edit- yes that was. cuz i remember the tornado that leno made. the twin turbo LS1. he converted it TO RWD.
