Runs like a banshee, except from a dead stop, it runs rich, that's right rich, you would think it would be lean, but no hesitation or stalling like when it's lean, it just sounds like it's missing until it clears up. I tried squirters and idle air bleeds. I put an 800 Edelbrock on it and it runs fine.
I also put the 750hp on my other car and it runs fine.
I need to do some things to make just a bit more power, either that or change the converter for more stall.
It's real close to running right, but I feel it will be worse at the track with better traction and more load on the engine at takeoff.
My combo:
1968 390 2V 68k standard bore
Cam Research 226/232 .540/.565 110 lsa cam
Survival Motorsports stage X heads with 2.2” intake and 1.66 exhaust valves
PI intake manifold
428 cj exhaust manifolds
750 HP double pumper carburetor
Faron recurved distributor
C6 transmission
ATI 2700 rpm torque converter
3.50 traction lock rear gears, 28" tall tires
Magnaflow 2.5” mandrel bent exhaust with modified stock exhaust tips
In a 69 mustang
One thing I know is wrong is that I used a Mr Gasket set that included .060 head gaskets, I feel it lowered my compression only a little but I'm sure I've got lousy quench which would account for some lack of torque. The pistons are around .020 in the hole so even with a .040 gasket it still will be bad. I'm not going to deck the block, too much work/money. The converter is stalling more like around 2400, I ordered it to be 2700, but I think the lack of torque is affecting the stall speed. The thing feels strong until I drive my 67 with the very mild, worse compression 460, then
I've got some ideas that I will be posting in the future, meanwhile I'm running out of time for cool dragstrip nights around here.
