SBC_400 Posted March 29, 2004 Share Posted March 29, 2004 This is not for a Z, but I know this a good place for the right information. I am about to build a budget street stock engine. according to the rules for my local track, the engine must be "stock apearing" and must run a rochester 2gv carb. what would be the best displacement and cam, and what head work should be done? this is a for a low budget dirt track camaro. what would be the best way to get some hp for cheap? thank you all in advance scott Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted March 30, 2004 Share Posted March 30, 2004 Do the rules have any limitations on Compression Ratios? Are there any rule limitationis on Cylinder Displacement? What are your ideas on which Cylinder Displacement you were thinking about utilizing? What are the diameter measurements of the Venturis on the Carb you will be using and its CFM rating? If this is a budget build, what Redline RPM were you hoping for and how long is this engine expected to last?

grumpyvette Posted March 30, 2004 Share Posted March 30, 2004 if youll post the rules, and budget your working with, Ill take a look and suggest something but not knowing the car weight,displacement,gearing, trans type,head restrictions,octane limits,cam,lift/duration,or compression limits makes guessing useless at this point, Quote Link to comment Share on other sites More sharing options...
SBC_400 Posted March 30, 2004 Author Share Posted March 30, 2004 OK, I dont have the rules sheet in front of me, but from what I can remember, it is fairly open, except for what I said about "stock appearing" so no alluminum heads or intakes, but we are allowed longtube headers, and the exhaust is limmited to a 3" pipe for each bank and must extend past the drivers seat and exit on the right side of the car. The car I am looking at buying is a 79 camaro. it is completely gutted and has a full cage. it has run at the same track I will race it at for the last 5 years, but the current owner has not had it scaled, so I do not know the exact weight. the current owner ran the car somewhat competitivly last season with an almost bone stock 350, he said all he did was change the cam, and heads, but he did not say to what. compression ratio is open, as some guys are running 9 to 1 and some are running 14 to 1, so octane is not limited either. so I think internaly it is pretty open, just cant look radical. and like I said before, a gm engine must run a rotchester 2gv carb. current rear end gearing int he car is 2.73 it believe, and hte trans will most likely be a th 350. last season with a th350, and a bone stock 307, i ran the car in second gear and it seemed to be a good combination. but the guys I talked to running this class said that with the 2.73 gears, they jjust runn in first gear the whole time. the track is just a 1/4 clay oval, fairly well banked on one and two, and pretty flat through 3 and 4. for the engine, I am looking for a a 327 or a 350, and the budget for the engine is $1000 or less. the less the better. the class is basicaly a sportsman class but it most closely resembles street stock in car preperation. and I am not looking for a track championship this season, as it will be my first year in this class. I am looking to turn some laps more than anything, and I want to be fast enough not to make a fool of my self. so I guess I am looking for what combination of fairly stock parts will give me the best results, and what cam would work best with that combination etc. thanks, and when I get home I will look through the rules and see if there is anything I missed, and post it.
