This Sat, last hurrah at the track with the 347ci motor. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well, looks like I will be taking the truck to a grudgefest this sat night. This will be the last voyage in the truck for this motor.

This time I will make sure I have all the timing in it on motor. Hoping to go low 11.4x on motor. Might take the 125-150lb tailgate off to try and go 11.3x NA

I know the N20 is working now since I took it to the deal in Dos Palos. It was a non timed 1/8 with no track prep. First stage was jetted with a 100 hit. Once I got rolling, I could get on the unit in first maybe 30-40' out. I do know I was doing about 102mph with a pig rich tune. Maybe I can get an 10.6x-10.7x on that stage out of the hole??

I'm also going to throw the 200hp jets in the second stage and hope it works right. Don't think I'll be able to use it out of the hole with the verter that is in it, but if I get on it going in to 2nd, maybe low 10's??

Sure would be nice..

That 347 has impressed me from day one. That new motor sounds awesome too.

Going up 71 inches with a 418 LS motor. Also putting my AFR heads on it over the ported stockers.
