Drag racers
« on: December 22, 2010, 05:38:09 am »
Does anyone else hit the strip on the weekends. I am curious as to what your running and how your running it. Before I upgraded to the solid roller cam I had the hydrolic flat EDL RPM series cam and stock suspension I was running 12.99 in the quarter mile. I have made some weight transfer adjustments and put in a 4 link. I hope to have her back racing and in the solid 12's or even 11's this spring.

Cam Style  Mechanical roller tappet
Basic Operating RPM Range  2,500-6,500

Not truck related but----
Have not raced in many years.   Back in the 70s - 80s I used to race a 67 Plymouth 440 GTX.
and a 71 Dodge 340 Demon.   I still do some work for some drag racers.  in fact, Larry Morgan's
prostock trailer is in the shop right now for some repairs.

My last trip to the local dragstrip(airstrip) was a disaster.  I got my tail handed to me by a couple fast cars(347 stang on a 200+shot and a H/C/I LS1 Camaro).  I had a bunch of issues though.  My truck pretty much turned off at the light(bogged nasty) and once I hit third gear it wouldn't rev any higher.  Turns out I had a bug in the carburetor and water in the fuel cell.
  You had a pretty nice 60ft there Acefoxx.  When I ran 12.8, I had a 2.1 or 2.2 60ft and 8.3 1/8mile. Are you running slicks or street tires?

Those were BFG drag radials, street legal. I will be switching to slicks this year. I found a matching set of rims that are 10". How lucky was that? $60 at a swap meet.

Dang! You got real lucky.  Your truck is running some good ET's for being such a mild combo.

thanks, I'm expecting to be in the mid to low 12's this year, maybe even the 11's. I don't really want to go much faster cause I like the streetability of it. And the faster you go the more expensive the repairs. That snd I don't want to put a cage in my cab.

Anybody else been to the track lately?  I got a buddy that put a 6.0L in his truck with a bigger cam and bigger carb than mine...I'd imagine it would be a bit faster than mine, so I'm looking forward to seeing his run the 1/4.  I'm planning to hit up our local races in March to redeem myself.

Sorry Ace, I didn't see this post before now...I was real busy with work, snow removal & other activities & wasn't on here for a bit.
 The basic rundown of my engine is toward the bottom of page 1:

1979C20, that's not bad for what it is.  I know some 1/2 ton trucks with more motor that can't run that.  What about that 2500HD you got?...I bet that thing is fast.
