We put the tune in it out of the cam only car that made 390 rwhp in it last Friday. It's running rich as hell and problably needs a degree of timing taken from it due to 11:1 compression. The setup consist of a 39,000 mile shortblock, GMPP LS6 heads 60.7 cc, FM11, LS6 intake, Shaner S2 T.B., ASP underdrive pulley, 12 bolt with 4:10 gears, and 18 X 10.5 Motorsport Z06 wheels. The car pulled 437/407 with no dyno tricks. We are going to do a wideband tune and see what she does. Also we will be adding a TNT F2 kit and try a 150-200 h.p. shot.

 

Sweet!! the F11 does okay on stock heads also....

 

WOW, awsome numbers..... thats a very nice set-up!

 

Time to go a little bigger......

 

Were the heads the only thing that was changed between the cam only and h/c pulls? If so, that's a very nice gain.

 

good numbers, graph looks good

 

he also added an asp pully and ported tb. but, the motor made the 390 in a different car that had stock 3.42 gears in a 10 bolt. the 4.10's in his 12 bolt are eating up 10-15 rwhp more than the 10 bolt did.

 

The other car was also cam only the engine came out of. Give me a call Jordon.

 

F11 on 112 or 114? straight up? any flycutt needed?

 

Are the heads out of the box?

 

It's a 112 lsa. and it fit with no flycutting.

 

These are out of the box, the only thing I did was change the springs to Comp 918's.

 

what head gaskets were used? pushrod length? cam in straight up?

 

gm mls head gaskets. 7.4 pr. straight up

 

sweet.keep us posted with the updated #'s

 

Will do, I'm trying to sell the FM11 right now, and move up to a FM13 on a 114 lsa.

 

will the FM13 fit without a flycutt?

 

That's why I want a 114 l.s.a. It should clear.

 

Are those heads ported? I know you said out of the box, but I thought Lingenfelter ported some of the GMMP heads. Great results either way.
