283 specs needed
 

Hi gang. A buddy of mine is wanting some help. Figured you could supply the information needed or supply a link to it. :thumbs:

In 1961 the corvette had an optional 315 hp fuel injected engine. I'm trying to find out the cam, head and piston spechs for that engine. The 315 hp was the highest output 283 manufactured by chevy and he would possibly like to mimic that engine with the engine he purchased.

Hope you can helps us out.:bigears Thanks :cool:

I was given a book by a neighbor that I believe has the info you are looking for, if you don't have any answers by the time I get home tonight I will check for you. Tom

That would be great Tom. Thanks for the assist. :thumbs:

Hope to get more replies from others too. :cool: :bigears

i really think the 315 number was generous at best....it was a solid lifter engine with 62 or 64 cc heads and 2.02 intake valves and 1"5/8 exhaust...from memory i think the cam was an 097=098 and compression was 11.25 to one....you could do a lot better with new after market components including heads and cam than in the old days but to each his own...good luck..jmho....:cheers:

Did you get the info you were looking for?? the book I have is "Corvettes Technically Speaking" looks like it was a limited edition printed in 1977, has about 30 pages of info/specs regarding 61, send me a PM if you still need any info, this book may have the answer. Tom

I'm not sure how much he really needs. I'll send him this thread and wait for a reply. Thanks to everyone.:thumbs:

Tom, I'll let you know as soon as I hear more from him. Thanks for your generous offer to help him out.:cool: Jean
