A heavily modified 302 in a '64 Corvette with 11.5inch slicks, M20, and a 5.87 rear gear (currently has 14inch slicks and a Doug Nash 5 speed, but hasn't ran it.
I'm curious how much money does he have invested into the motor? Considering a Nascar V8 doestn't rev to 9,000rpms and those engine are $50K a piece and only good for one race, yet your engine rev's past 11,000rpms and the engine holds up all season? What RPM does he shift at? If he launches at 11,000 he much shift at 14,000rpm or 15,000rpms.
Just curious about the engine, sound impressive. :thumbs:

Nope, you've got it backwards. He is passed the redline at 11,000. When the clutch is engaged the engine RPMs drop, putting him right into the powerband. He'd upshift at around 9,000rpm. The block has two sleeves in it right now, so it can break, but not as often as big blocks since they have way too much force into the thrust face of the cylinder. It is built with many factory components. He still has a points distributor. Forged internals, 13.5:1 compression, factory iron heads (that he spent 90 hours porting himself), big tunnel ram with two 600cfm Holleys. He doesn't have too much money invested into it as he built it on factory worker pay. He spent maybe 8k a year on it while racing competitively against people that spent about 50k a year on their cars. He quit in '87, but was ready for the '88 season (so the whole car was built on '70s and '80s technology) and since he had 4 kids now and the Uniroyal plant was closing in a few years he built the hardware store my mom runs. Oh yeah, and he has had a fused right (clutch working) ankle since the early '70's from a car accident in his 4 door '57 Chevy.
Amost all Pro classes ( Pro Stock ProMod etc,) in drag racing use manual transmissions like the Jerico, Liberty and G-Force, These transmissions are expensive and you don't need the clutch to shift. They are by far faster than any automatic out there. :D
True, but since there is no clutch to shift you can't compare it to traditional tranny's. It's not an auto, yet it's not completely a manual.

I'm pretty sure the Jerico used in the CHP test was not a clutchless Jerico.
I think these discussions always come down to 1/4 mile times as that is the easiest way to get hard numbers for comparison.
The truth is, the manual vs. auto argument can only be solved by one person, you. It is a preference and every has their own preference.
I'm staying with an automatic! Sticks are fun, but I plan to do a lot of sunny day cruising, may only see the dragstrip once or twice when I'm done. The auto makes it a lot easier to suck down the Big Gulp! :lol:
If..and I reapeat IF you can get a manual to hook at the track and your a good driver it should out et and out mph a auto car. The difference is all in the 60'. It easier to get the auto to 60'. Put a good converter in it..some sticky tires and let her rip. You will also notice that at the track if an auto and manual cars run the same et. The manual will usually out mph the auto by around 3 mph. But..the auto will out 60' the manual. It all boils down to you..what do you want to use the car for. Full out race car...an auto is gonna be more consistant and easier on parts and cheaper to keep running(less drivetrain shock = less parts snaping). Now...if you take away that 60' advantage by putting lots of money in the suspension of a manual car you should be faster all other things being equal. Now on the street..from a role..the manual is gonna OWN the auto if they are close in HP.
I have both. My vette has a full manual valve body TH350. I love it. I put a tci 3600 converter in it and some Nitto 275-50 drag radials and cut low 1.6x 60's all day long. My 95 Formula has a t-56. I have TONS of suspension modifications and have to run a 28" slick to get it to hook consistant. But..it does go low 1.5x to high 1.4x 60's now leaving at 5500.
Mine is an automatic. I perfer it over manual trans because to the wear and tear on your muscles and joints. Stop and go traffic? Where I live stop and go traffic is a monster. Forget it. Manuals sux.
I like the way my vert "squats" when you put it drive as if to say Im ready to run!
:lol: welcome to the forum, vettinator. you going for :troll status so soon? :eek: *(pssst, just between me and you, i agree!)*
oops! did that print out! :bb
:jester
My buddy with a 240 Z told me that about my car. I replied, "Real sportscars aren't from japan either." :cuss
"AUTOMATICS ARE FOR WOMEN."
I used to feel that way too, but after looking at more than a dozen cars and only finding one four speed (that needed a whole lotta work to be as nice as the car I ended up buying), I figured I could live without it. I think my car probably belonged to a woman when it was new - aside from the auto, it's got power brakes, power windows, and a/c - and the base engine (for now).
Regardless, my car is still a blast to drive, though my next car will probably be a 4-speed. They are fun to drive, and there's a lot to be said about the feel of banging through the gears.
