Drag race inductionfearsomefairmont 05-13-2004, 01:12 PM Hey Folks, I know alot of people in the forum are import folks and never touched a carb in their life, but I was looking for the best carb type for a 351 cleveland 4V in a '78 Fairmont (2700 lbs, toploader 4-spd manual, 4.10's). Here is the motor: 11:1 compression (100+ octane gas) Solid roller cam, 248/258 @.050 duration, .668/.678 lift, Fully race ported heads (320/250 cfm) with epoxy filled intake ports and backcut valves. High rise single plane intake w/individual port runners (parker funnelweb) RPM range 3000-7000+ I have heard many varying opinions about carb size and choice for these cleveland motors. For a normal 350 size motor, a 700 cfm would be about right. However, for a similar setup I saw a guy running a 1050 cfm dominator carb (500+ hp though, even with milder cam)! It seems HUGE for a small block. This obviously isn't a daily driver machine, just a fun car to drive like I hate it :~) Any suggestions? Andy DynoDon 05-18-2004, 02:12 PM Don't have a clue... But I did read recently where a known shop (can't remember who) said carbureted cars should have about 6in vacuum at WOT. Probably to insure adequate metering at the carb.. vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
