the ones i had were not any taller than stock. but i had them on a 74 formula. are you talking about the finned ones?

 

welcome.

 

Stock booster, how big?? What do your valve covers measure now and what do the M/T covers measure?? Do your present covers clear good, go on and off ok?? Pix would help.

 

Stock boosters are 11"

Stock VC's have rounded edges, so it's not enough to merely go by VC height. An aftermarket VC, of the same height, but with a square edge, will give trouble. Add poly locks to that, and forget it.

My advice to the OP, if you truly desire the aftermarket VC's, simply buy a cheap, 9" booster and swap it out. Its a fairly painless job.

 

Almost everything on my car is still factory. I haven't measured anything yet just thought about it after I left the shop haha I will take some measurements and see what fits thank you

 

Looks sharp, single plane intake I see meaning some hp to that motor? Looks pretty tight to the booster, just an observation but I see it's rusted a little, are you planning on replacing it and the master? If so put a smaller dual booster in that's what I did for clearance.

 

Stock Boosters are 11".

Aftermarket VC's can have trouble, if they're factory height, and not radiused like the factory VC's... ALSO, taller valve trains will hang them up.

 

On my 65 the MT's cleared a stock booster. I do have a summit front disc kit on - it uses later stock GM components - pretty sure the booster is 11" no issue getting valve covers on or off.

I have stock valve train with poly locks. if you are running a taller valvetrain and need to space the covers off the head you may have issues.

My old 67, with a stock booster, had roller rockers and polys. I tried to run plain-old-edelbrock-chrome VC's, same height, and NO Dice!

Back then, I wasnt wise enough to swap boosters, but I was definitely dumb enough to run stamped rockers on #7, while everything else had sweet anodized rollers!
