Howdy,

I finished swapping my old E-Performer 600 for an E-Performer 750. Here a some before and after shots.

Before:

After:

The truck runs much smoother and usually kicks on after 1 or 2 cranks. So far, no peddle pumping required.

Enjoy!

BTW, I realize a stud is missing. The PO had drilled out the mounting hole on the other carb and used a standard bolt instead of a stud.

Why'd you step up to a 750? I always thought that was a bit much for a 350.

jdheff1982 · 10-07-2011, 03:50 PM

Not a 350. It's a 355 with flat top pistons, scat crank and rods, big muther thumper cam, and full exhaust. Plus, it was on sale for $200 @ Jegs.

The motor would disagree

well What did you do with the old one

? 750 thunder series Worked great for my 350 in my camaro. It was a stock 350 with performer intake and hedman headers.

RandyP · 10-07-2011, 05:18 PM

Well, yeah... for 2 bills I'd have gone that route as well!

I boxed the old one up. It would cost roughly $100 just to rebuild the thing. Not sure what to do with it, honestly.

Next thing in line is to upgrade the dizzy with a MSD HEI upgrade kit along with MSD wires. Trash that Accel junk.

I see you have headers. What do they run down to? MSD has alway done me well. well instead of letting that carb rot away you should send down my way

I'll reimburse you on shipping!

I think the headers run into 3" pipes with flowmasters. I am uncertain of the series for the mufflers.

I'll have to get a vid up of the truck running soon.

That should Flow nicely with your motor. Id like to see it running.
