302 tuning help!!!!

[blackmag17]

48 IDA's are new to me, and I need some help tuning them. My car is running rich, all the plugs are black. And it lacks power. These are my engine specs:

302ci, 9:1 compression, steel heads: 1.940 intake/1.600 exhaust, solid lifter, duration= 0.050 @ 236, 0.528 lift, 110 lobe separation, 106 intake center line

Webers: 37mm, 150 main jet, 200 air jet, F7 emmulsion tube, 120 idle jet holder, 65 idle jet, Inglese 3 1/8" velocity stacks with nylon booties

I need to get the car running well so I can see what this motor can really do!!! Any help is much appreciated.

I'll give you a few suggestions.

9.0:1 is not enough for 236@.050 solid cam, you need high 9s at least, my 308 runs 242@.050 at 10.3,
my mates 355 runs 238@.050 at 10.4:1.

I'd try an emulsion tube change to F2, my 304 runs fine with F2s and a book I have states F2 for chokes in the 36 - 40 zone.
Choke tube is the first thing to get right, 37 should be ok for your 302.

Do a search through the forum search function for "weber", there's a stack of reading in here.
