going large
Hi all, was looking for advice on going to a bigger motor. I currenty have a 502 gm dart 345's dart intake 10:1 pump gas motor with nitrous in my 67 camaro stock front chassis. Car has gone 10.30's on gas and has run a 9.23 w/400 shot. I was wanting to upgrade to a 582 short deck to keep things simple but was thinking if I am going large why not go all the way. This means of course a tall deck motor. Found out Lemons says they do make headers that will work with a tall deck block with a conventional head and a big chief head in the 67-69 camaros. I don't know about putting a big chief head on this car, could be asking for more fitment issues. I don't have a lot of room with the set up I have now. I don't have any power steering/brakes or any accessories, so I am thinking this could be done with the conventional head. Should I go 622 or 632 or? What head? dart 385cc? What about the 18 degree heads from dart that you can use all the conventional parts with? Suppose to be good for about 50 hp over a 24 degree head. Want to go about 11:1 for compression for this limited street strip car.
Shaffirof has a 632/900 and a 632/1000hp big chief Ultra street motor. Anyone recommend these ultra street engines? Anybody here that has put a tall deck motor in a 67-69 camaro stock front chassis? Oh, I have the big cowl hood. I am tempted to get the 632/900 motor just don't know if I am asking for trouble. Surely someone here has done this. Thanks for any advice...
