Yeah, I just picked up a 350 4-bolt block and I had a couple of questions. Will the oil pan from my 305 TBI fit on to this 350. And one more. This other source has some 75cc heads for sale for pretty cheap. What cc are y stock heads? So would those be better or worse? Thanks, sorry for all the q's I am really excited. L8er you all,

 

Yes the oil pan will swap over, i wouldn't buy those heads with the 75cc chambers, try to find some 64cc or so, so you can maintain some compression.

 

you have a point there. It is a toss up, better compression, or freerer(sp?) flowing. Did anyone know the stock head combustion chaber size though? Thanks for the info there.

 

Well, my orgional eng. was a 305 L69 and they had 58cc.

Auggie

 

Well stock combustion chanber size varied from about 64cc to 76cc in stock form, but the 76cc chamber suck because the compression ratio was about 8.0:1.

 

thanks man, so how would I tell my combustion size? With the vin number? Or that thing in the glove compartent box? Or where? thanks for all the info ya'll.

 

easiest way to do it is to get the casting ## of the head, it will be under the valve cover.

then go to yahoo or snap and type "chevy casting numbers"

 

ok, I will check that when I take my valve covers off of my 305. Which should be really soon. Thanks man,

 

Go to mortec.com and find the head casting number it should tell you about the head and the combustion chamber size.

 

Alright will have to wait till I get my valve covers off though, thanks anyway.
