So did your clutch fit and spin freely or is the tranny still just bolted to the engine with nothing inbetween?

The Comp and the LS7 were nearly identical. I also found that if you machined the piston on the V8 lifters down a little bit, you could install them in the 60* and turn them into solid lifters.

Pics tomorrow


What's purportedly wrong with the stock roller lifters? Joshua tried the lifter modification provided by the 60 degree V6 store and had trouble with it. You may want to check with him about it.

I believe It's going to take a bit more than that to make it safe and solid for the 3500 to do 7k rpm routinely. Superdave on 60 degree took out rod bearings at least twice in his 3500 from what I recall and according to their lit.., GM did an enormous amount of work in flow, weight reduction and part strength from what I read to get the LS7 to do 7000 rpm. Keep in mind an LS7 lifter has to do more work weight and ratio wise (1.8:1) rockers than the 3500 lifters relatively speaking.

Just be sure you investigate this thoroughly as lifter spring strength also varies relative to the valve spring strength used not to mention how lifter pump up will affect/support the lifter spring. Just don't take any chances that can create problems is all I'm suggesting.

Good luck with yoru build man! I love to see turbo Fieros! Since you are in Pcola, do you ever go to the swamp meet @ the Boardwalk in Oakaloosa? Maybe we could have a little run, eh?

I also destroyed my lifters that I was going to modify in an attempt to clean them. so it looks as though the real deal will be on my 3500's lifters.




Where are you going to mount your ECM? Thats one of the few things I still have to do on my 3400 swap

You may have covered this already, but what are you doing to make up for the fact that you are turning your power steering pump backwards?

Forgot to ask you about the clutch. You have a Centerforce dual friction clutch. Is it for Cavalier or something else? Did you have any clearance issues? I´m doing F23 and 3,4 DOHC swap and used Ram HD clutch for Fiero and had clearance issue which solved by taking a slight amount off from the transmission and three corners of the clutch. Planning also to add about 1 mm aluminum between the trans and engine. There is no touch at the moment but on operating temperature it could toch and this 1 mm could avoid it.
Do you still have the Thelin rear trans mount. I´m willing to buy it from you.
Keep on the good work and let us know the results.
