Just another build thread - Sort my combo!

This'll be my first real performance build, so I'm gonna lean on all your experience a ton!

I have a low-compression 440 out of an RV that I'm building for my barracuda. I have a 727 with it, but it has the shortened tailshaft with the u-joint yolk instead of a normal slip joint. I'll have to sort that out, but I have the 904 to use if all else fails. The car's got a LSD ford 8.8 rear with 3.73s already in it. I dont have a dragstrip within 300 miles of me, so really my main hope is to have a great time at stoplights and car meets!

I have a set of KB pistons with a 2.067 compression height, should be good for 10.6:1 with the setup I'm planning on (or around 9.6:1 if i switch to 84cc heads or something), and I just ordered new bearings all around, arp rod bolts, otherwise stock rods/crank.

Edelbrock 750 carb (mechanical secondaries?)
Performer RPM manifold
E-street 75cc heads
COMP 1621-16 1.5 roller rockers
Hyd Flat tappet cam, need recommendations here. Looking at a few of COMP's XE cams

2500-3000 stall converter, waiting till i figure the cam out

try-y shorty headers, maybe some good TTI headers if you think i can work them in without cutting the fenders up? I hope to keep the power steering, but I'm not afraid to convert to manual if I need to.
