Here is my setup, an 86 RX7 with a 95 Lt1 block and heads, Mac headers and with exhaust, and t-56 trans with stock 4.10 rearend, so it weighs about 2700 lbs. I have converted it to carb. I plan on upgrading the heads and cam, but that is later down the road. I was wondering what the best carb would be. I plan on driving it almost everyday. I was wondering what the best carb I could run for my setup? If anyone could give me their opinions on carb choice it would help me out alot.

thanks, Nicholas Les Chander

 

ball park calculation is:

(efficiency*(cubic inches*rpm))/3456 = cfm size carb

(.90*(350*6500))/3456 = 600 cfm

typically folks size it up 1 or 2 levels so a 650 or 700 double pumper holley 4150 would be a great choice. 750 would be a bit much unless it was more a race application.

Barry Grant Speed Demons are nice, but pricey.
