I can't tell you much for intial timing yet, but I would think 12-14 would do much better. How do you have your curve set on the distributor? Using vacuum advance or mechanical?

There, answer these any we may have a little better picture of what you have.

INT. 262 EXH. 270 INT. 218 EXH. 226 Lift INT. .493 EXH. .512 lobe sep. 111 degrees Roller lifters compression ratio 10 if I remember right. Weiand intake dual plane Set from Holley probably should check I'll try 12 -14 on timing and to fatten up the carb that would mean to turn the screws in? And not really sure how to adjust the rockers. I never had rollers before. Thanks for the help. It is in a 57 Willys Wagon with 456 gears and an automatic. Pertronics distributor vacuum advance
