64 Vette….Rebuild 2.0

They are 2.02/1.60 with some port and bowl work.

Rick the double humps were used on a lot of engines, and starting in 64 the solid lifter engines as well as some higher performance (I.e. 327/350) had 2.02’s as well, but many sets put on milder engines had 1.94/1.50 sets.
So the camelback heads have higher compression even with the 194 valves or what makes them special?
 
Well it was the 60’s….IIRC they were 62-67cc combustion chamber w 160-172cc intake ports. They were in production for 9 model years 62-70, ending w the LT-1 of 70.
They were the best head available until Chevy came out with OTC race heads. then the aftermarket brought out aluminum.
Vortec heads are better performance, but not as durable.

What tires and shocks are you using on the rear ?
 
Goodyear Eagle sport, 225/60, and Monroe sensa tracs, those will both change when I get around to doing the disc brake/31 spline outers upgrade. Not sure to what though? A dual adjustable in rear and maybe a single adjustable up front. Also will make a spring rate change front and rear. These are more autocross rated springs in it now.
 
If you are upgrading shocks I would always recommend double adjustable if it's in the budget, both front and rear.

For the front it lets you adjust the rise and fall rates independently, which is very helpful, especially so you can change the rebound(rise) and still leave the compression stiff enough to catch it on the way back down if needed or keep the front up so it doesn't unload with lower power levels.

And for the rear you want to be able to adjust the hit on the tire (rebound) separately vs the compression. It's very helpful to reduce 60 fts and ET.
 
Been looking at the QA1 DAs. That what a lot of the stock appearing guys are running. Re: small tires, fat cars
 
QA1 are nice entry level shocks with not as much adjustment range through the click values. They are decent street shocks for adjustment but the full click range doesn't do much to the damping rate. Put it on full compression as much as it has and still not absorb the touchdown and stop the bounce for example.

You'll get a much better result with Afco or Strange without breaking the bank, or getting a second mortgage for Penske or Santuff, etc.

Will these Afco or Strange shocks hold up for heat on something running 90% street and/or dodging pylons? I know the drag dedicated shocks advised against street driving due to excess heat build up
 
I turn the compression all the way down for street driving and then you know how many clicks they need to be for the drag strip to start with.

Afco also builds shocks for other stuff not just drag, in fact I think they started more in circle track.

Of course everyone needs to prioritize what the vehicle is for, everything is a pro and a con.

I haven't had any issues driving my Afcos on the street, but I don't drive them that many miles either, its not a daily.
 
The street use is a major concern for me as well. 90+% of the time its a streetcar. I’ve made 5 passes in the last 13 years w it…lol. But certainly more in the future to where something adjustable for street and track would be nice to have.
Front springs will change from a GM Daytona racing spring to a more common base 70’s small block spring.
Rear will lose a couple leaves to lighten the spring rate as well. That springpack is 2” shorter to allow for wider wheels.
right now the ride is firm but not harsh, and little front end lift/rear squat at the strip.
or as long as theyre using oem mounting, I could keep the sensa tracs for street duty and spec a drag shock for strip.
 
If you took everything off my car that wasn't recommended for street use it would be comical, and I drive it on the street more than the track.

I don't think changing shocks is necessary, that's one of the benefits of adjustable, especially double adjustable.

The bigger question is do you want to prioritize handling in the turns or straight line performance. I think that's a bigger tradeoff in some ways than the street vs race parts.

Pennington. I believe his Dad owns a couple ZL-1/L-88 Corvettes and Camaros.
he drives the 9 sec Orange ZL-1 Camaro clone in FAST race series. From the east side of Mi. They race at my local track a couple times a year. Amazing they get that car down the track on oem tires! 540/850hp all aluminum looks like a ZL-1 still.
