Customer q:
I can't decide between #835171 and #835162 manifolds. I have a 454 big block over 0.020 with 30cc piston, a .625/.639 hydraulic roller cam and a 502 rectangle port heads. Which intake would work best? Single carb or Dual carb? And what size carb should i use? I have an 800cfm Holley carb. If i went dual, would I use 2 600cfms? Thanks

JEGS ANSWER:
Thanks for choosing JEGS for your automotive inquiries. I would suggest a single carb manifold for the combination. The 800 you have currently will work well with a single. If you simply want the look of dual carbs, I would suggest using 450 cfm carbs. If you need any help, we are here 24/7.
