Hello, does anyone have hood clearance difference between stock 64 sbc hood and "other" c2 BB? hoods. Looking for a maximum difference to use for add on toys, lol.
Thanks,
Frank, in cold Chicago.

Frank,
I have a aftermarket BB 67 Corvette hood that I had on my 67.
Since it has the hood prop hardware on both sides it will fit all C2's from 63 to 67.
So since it has a "universal" hood prop location it I don't think there are any limitations, so this type hood will fit all C2's..

It is also for sale, if you are interested.

Thanks,
I need to know how much more under the hood clearance a bb hood has over a stock 64 hood. Does the "hump" on the hood provide inside space also.

Frank I had a single plane high rise with a 2 inch airfilter that just touched the hood. Went to after market 67 BB hood and replaced 2 inch filter with a 4 inch filter and have an 1/8 clearance. Based on that I would say you pick up 2 inches with 67 BB scoop area. Hope that is what you were asking.

Frank,
Our weather is like Chicagos so I won't b going to the garage until tomorrow.
Temp should get up to 10 or 15 degrees, so I should be ok.
I'll do some measurements and get them to you.

Frank,
Rough measurements indicate that with my repro 67 hood you gain about 2 1/2 inched in clearance in a area starting 16 inches back from the front hood rib. The raised ares is about 19 inches wide and 22 inches long.
I have attached a few pictures FYI.
I hope this helps.

Thanks you all. that's a significant amount of extra space. was looking at FI throttle body from summit racing with single plane hi-rise.. got something to work with now. Thanks again. and Merry Christmas.

Frank that is what I have on my car but it is Mass Flo EFI. Check to see what kind of air cleaner they recommend with the EFI system your looking at.

frankgv

thanks, just got your message.do you have the bb hood and how do you like the Mass Flo EFI ( is that from summit?)

RJ1

Frank I added the big block hood see post up above. Mass Flo is great. Purchased from Xplosive Performance. They are a forum sponsor.
The hood Bruce has for sale will do the job for you.

Thanks, do you use a return flow? what motor? and what did you replace, a holley??? what are the benefits, better acceleration, lower et's?

Frank Mass Flo is a port injection so has to have a return line. Rated at 1000 CFM. Engine is a L-79. Added EFI system, aluminum heads, and headers. EFI gives all the benefits of current daily drivers. Self learning, start up, fuel economy, ect
