Correct Hood for a Big Block
Hello All,
I am putting a 454 motor into my 1970 corvette. It had a 350 with a Edelbrock performer intake and holley carb. Will the big block with the same intake and carb fit under the stock hood? I would be putting on a stock big block/LT-1 hood. I do not want to go to an L88 type hood. Does anyone have any experience?
Thank you in advance,
Dhasso

The performer and holley should clear with a low profile air filter.
I had an edelbrock 1407 on the stock intake with a 1/2" spacer, and low filter, but I squished the filter slightly with the hood closed. There isn't much room, even with the BB hoods. That 1/2" spacer was the difference from clearing and not in mine.
I don't know where you're located, but I am selling my LT-1 style hood in favor of an L-88 wiper delete.
If you're interested PM me.

My experience is as follows :
I installed a 454 with a stock intake and qjet in my 76. It fir under the hood just barely using one of the triangle mesh air cleaner. Then I installed an ecklers low rise hood ( about 2" above stock ), and was able to install a regular 14 x 3 air cleaner. I then installed an edelbrock performer intake. I was not able shut the hood untill I installed a drop base on the 14" air cleaner. Right now there is only about 1/8" between the round head bolt holding the air cleaner down and the hood.
I am hoping that when I install my L88 hood I just bought, I can go back to the regular base for the air cleaner. The edelbrock performer is a pretty high manifold compared to stock.
