So I finished my 318 for my 87 D150. It's a 90 318 with 714 swirl port heads with stock valves and a 5 angle valve job. Hughes whiplash 318 hydraulic roller cam,comp 901 springs,locks and retainers. Eddy performer intake on top with headman long tubes. Msd billet distributor with a 6a box,8.5 mm wires, summit 2800-3200 converter,3.55 sure grip rear. I have two carbs that need rebuilt. One is an Edelbrock 1405 and the other is a Holley street avenger 770. Which one will be the best fit on this mill?
