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?

well guys, not much to report, I've been making a diligent effort to get the wiring sorted out. I'm also waiting on parts... I did get the injectors installed, along with the 3400 fuel rail/regulator. I've also found a location for the ECM, but I'll need to make a splash guard for it. 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?

it's a standard rotation pump, with a reverse rotation pulley.
