Hello all,I jjust found out our local track will be going to two barrel carbs only next year. I've got a super stock with a mild but strong 350. It weighs 2650 lbs with driver. A quick look of whats out there indicates the Holley 4412 would be best bang for my buck, but what about intake? I have no experience trying to make a two barrel sing on a 350. Do I run a 4 bbl intake with an adapter or is there a great 2 bbbl intake I need to look at?I'll keep an open mind about any suggestions, but the $300 for the Holley and couple hundred for a performer (or equivalent)sounds decent to my wallet. I am on a budget.Thanks in advance!Doc
Sorry, I forgot some important info. I specifically mentioned good torque because I'm trying to keep RPM low. We race a high banked 3/8 mile dirt track. At the end of the straight I am at about 4500 RPM. I need something that pulls nice in that range.There are guys who go through three or four or motors per season and I have no idea how they afford it. I can not! I don't mind spending more where it counts but I can't throw it away like that. If I keep the RPM low I expect to get my money's worth outta my motor.Thanks again.
other racers in the 2 bbl class use the gm marine 2 bbl manifolds..there are several articles here on 4412 carbs and on the rochester 2g carbs...http://www.circletrack.com/enginetech/ctrp_1101_rochester_2g_carburetors/viewall.htmli wonder if you could get away with one of the RARE quadrajets that have not had the secondaries opened up...they are blanked off.. those are a 2bbl... but they bolt only to a 4 bbl manifold..here are some 4412 articles..http://www.circletrack.com/sch/02/4412/articles/
a forum post on a similar subject..http://forums.circletrack.com/70/7358328/dirt-racing/gm-cast-iron-intake-please-help/and don't forget...that if you are on a budget... and have a manifold with a holley 2 bbl flange... you can if the rules allow it... ford/autolite/motorcraft 2 bbl carbs..
Go through 3 or 4 engines a year? They better rethink their building habits and driving habits to keep the engines alive.
