It was built to run a carb and distributor in a specific race class. FAST sent us a crank wheel and trigger for an SBC and we adapted it to the front of the pulley system.

Long story, short, it just doesn't work, even though FAST is positive it will.

I pulled the plug.

We're expecting a 416ci LS3 based Mamo Motorsports built motor on Wednesday. It will get the FAST XFI Sportsman EFI and keep the look I want in this car. We lose some RPM, we gain some weight and certainly gain about 125hp.

This destroked LS2 gets a GMPP front timing cover that takes a distributor. Might get dual quads that I have, might get something else, but I have a 31 Ford to put it in. I think it will bug some guys... it looks like a Ford motor, but has GM stampings on it? :)

JJ, this project has fought you since the beginning, so keep pushing. You'll get there. So...the issues with the efi? No idle?
Did you get your flush glass installed?

We couldn't get the timing right. It was just too much to fight.

Haven't ordered the flush glass yet.

Another 100+ HP I'll take it !

You took care of two birds with one stone.

Where we sit, waiting for a new oil pan and baffle, since it's a 4" stroke and a low clearance application...

Driving me nuts.

At least I got to weld on AN20 fittings to the water pump and radiator... that's a -20 on my thumb. Seems a bit silly, but it's the look I want.

Just WOW!!

Is that a GM performance crate motor or???

It's built by Mamo Motorsports. A wee bit more juice than a GM crate.

All my other cars will be done with GMPP connect and cruise crates though. I've learned my lesson with the LS2 that came out. No more "it should work" applications. Tried and true will be my new name of the game.

Yep - although this Mamo motor is loads more than any GMPP motor, so it does have that going for it. It's still much simpler than the LS2 based RPM motor that came out of this car, which is also getting simpler.

Nice looking motor, Mamo knows his stuff .
