How would a L75 Corvette rate against a L84 Corvette at sea level, 68 degrees ambient, rel. humidity 64 percent. The fuellie has close ratio, with 4.11, and the L75 has wide ratio, and 3.08. Same tires.

Re: Drag Race
The L-75 hasn't got a ghost of a chance! The L-84 has about a two second advantage in the quarter mile with the same driving technique.
Actual times would depend on how hard you want to beat on it in terms of launch and shift techniques. Period road tests of L-84 press cars with 3.70s yielded quarter mile times in the mid fourteens at about 100 MPH.
An L-76 would be close as the L-84 doesn't have much of an advantage until the heads are reworked at which point the larger/more efficient FI manifold runners will asert their advantage over a conventional carburetor manifold, but in OE form the heads are the limiting factor on power.

Re: Drag Race
Street tires '65 FI with 4:11 and CR using factory offroad exhaust will run low 14's in the 1/4 at 800 feet and 75 degree ambient. I have the time slips and trophy to prove it. An L-75 is a mid-15 second piece generally speaking.Bill Clupper #618Comment

Memories from Puyallup
That's: pew-AL-up (Washington), an Indian word!
Best I ever ran with my 340 HP circa '65 was 14.42 @ 102 with the cutouts open on hard 6.70-15 Michelin X tires. With my 3.08 gears I shifted into second about half-way down and went through the lights at the redline in second.
I just drove it out the the hole like a normal start from a stoplight. Any attempt to drop the clutch would just set Michelins on fire. The 3.08s are definitely not drag racing gears, and I knew that, but I wanted to see what she'd do. With 4.lls, even with the Michelins, I would have been in the low fourteens and a set of sticky tires like Atlas Bucrons with 4.11s probably would have gotten me into the 13s.

Re: Memories from Martin Michigan
In 1984 I ran my 65 SHP 4 spd with 411 gears at Martin dragway during a Super Sunday Chevy event and ran a 13.65 @ 103mph with crappy Cocker tires.My leg is still shaking.
I even got best restored Corvette----it was a good day!

Re: Memories from Puyallup
atlas bucrons were good for the drag strip but were not good for high speed driving on the PA turnpike. a friend had them on his pontiac and after some miles at 100+ MPH we had 2 come apart. good thing that the service stations on the pike back then were esso and they had replacements. we slowed down after that. they had a wear replacement warranty on them so we would buy 4 new ones on saturday,run a autocross with our corvetttes on sunday and take them back on monday completely worn out. this only lasted a few time and the dealer told us we had to keep them for at least a month before bringing them back.Comment
