New guy here! Just bought a 72 Camaro RS. Came with a 350 from a 1970 SS. It has an Edelbrock Carb "1406" if that means anything. Engine and tranny are stock from what I can tell. I was told that carb may be too big for the stock motor. I have the stock Carb, but needs a rebuild. Can anyone tell me if the "1406" carb is too big for the stock motor? seems to run well, no probs. Just want to get the most performance till funds say I can replace the motor! Also, WHAT CAN I DO to the stock motor to get more performance? I want that "potato" sound, lopey cam. Any suggestions? Thx

 

Hey welcome. Your Eddy 1406 is a 600 cfm. It's not too big, actually it's teetering on being almost too small as your engine sits now. I would check the numbers on the block and heads just so you know for sure what you have there. http://www.chevy-camaro.com/chevy-ca...oding-help.asp "What it came out of" doesn't guarantee that it was the original engine in that car. There's a lot you can do to your engine, it all depends on your skill level, and your wallet. If you're not familiar with the fundamentals, then this book can give you some background, ideas and inspiration: http://www.amazon.com/How-Hotrod-Sma.../dp/0912656069

 

I actually did check the engine numbers via nastyz28.com. The motor apparently is from a 1970 Camaro SS. Can anybody tell me what the timing should be on that motor? I been trying to google it but no result. Just wanna get the most performance out of it until I replace the motor. I wanted to start with bolt ons first, then a cam. Didnt really wanna do head work, rather put the money towards new motor.

 

Timing "by the book" is a starting point. Start with 10 degrees before tdc and see how the engine performs. Use your ear to go from there, listening for ignition "ping" (marbles in the cylinder) while under a load. If all is quiet, advance the timing another 2 degrees and road test it again. If you're already getting pinging at 10, retard the timing 2 degrees. The "best" place to be is with the most advance you can get out of the engine before it pings. The type of gas you run will have an effect on where it pings too. If you're running premium and set the timing, you want to stay with primo. If you're using the cheap grade of gas, your timing will have to be retarded more than with premium. You'll get more performance out of the engine running premium, because you can advance the timing more, but it comes with a price since the gas costs more.

 

Ok...what size carb should I be running with this motor? Any sugg on headers and mufflers? Also, what viscosity oil should I be running? Wanted to use Mobil 1.

 

Oh, what spark plugs u guys running and what should the gap be?

 

I wouldn't run a synthetic, unless the motor is fairly new. Changing an older motor, Tor one with many miles) to synthetic oftens causes problems with oil pressure. I've had an issue with trying that and having my engine start to smoke after changing to synthetic, and a frirend did that to his Ford 460 and lost all oil pressure.
I changed back and it stopped burning oil, but my friend's 460 never did fully come back to normal oil pressure, even after multiple oil changes with petroleum based reg. oil.
