OK i am going to rebuilding a motor from a 75 corvette i am thinking about getting this rebuild kit since it needs new rings i mise well get everything else freshend up. would that compression ratio be alright for pump gas. i am going to be using a performer rpm intake holley 650 carb. what would be a good cam for it. http://store.summitracing.com/
part # FEM-MHP134-000

what kind of power am i looking at also thanks

 

what heads are you going to use. and what cam. and headers. what rpm range do you want the engine to make power in

 

i was thinking some sportsman 2 heads but what would have to be done to the stockers to make them work till i get the new heads i have hooker shortys dual exaust with race bullets its going to be a summer daily driver and race on weekends not sure what cam. rpm2000-5500 i have a turbo 400 with a 3500 stall and shift kit but am not sure if i want to put that in just yet. what i really just want to do is get the motor back in the car so i can drive it some more this summer and save some cash to get the heads later and i dont want to have to pull the motor agian to put the new pistons in.

 

would i be able to use that rebuild kit with those heads with that cmpression ratio i dont know if it matters or not and what
were the valve sizes for that motor.

 

the sportsmanII heads are a good choice so are the dart iron eagles. you can make a lot of power with these heads.I would run the 10.3:1 compression with a comp xe284h cam, preformer rpm intake,750carb(holley),dart or world products heads 200cc port 64cc chamber,hooker (long tube) headers or at least headman headers. shorty headers dont scaveng very well at all and the collectors are to short to flow well. a good set of rods and a crank and your done this will make 500hp. with your th400 and 3500rpm converter this would be a good match. you will need 3.73 or lower gears

 

what are the casting # for the stock heads then I can tell you what the valve sizes are

 

i just found out there the smog heads 1.94 1.50 thanks tho

 

yea i read the post the 882 head was not stock for a vette

 

wounder what they were from beacuse the guy had it in his vette.

 

truck or big car heads the exaust port sux on the 882 heads and the chambers are huge at 76cc (low copression yuk)

some 882s had 1.72 intake valves
