    I just signed on to this board in hopes of connecting with someone with information about GMC six bangers.  My father, brother and I built a GMC 6 powered drag car in the 70's.  We campaigned the car in NHRA's NorthEast Division for about 5 years with some modest success.  Well, life got in the way and we ended up selling the car and sold the engine separately.  I recall that my Dad said that he had sold the engine and extra parts to a "Bonneville racer".  It would be cool to find out if the engine did indeed go to a LSR effort but that is not the reason why I am here.  Well, my brothers and I are nearing retirement and we decided to replicate our dragracer from our youth and compete in the "nostalgia drag races" that have become popular.  We also decided to do it as a tribute to our Dad who had passed away.   
    Parts that were available 42 years ago are little harder to find nowadays.  The engine that I built back then was a 320 c.i. GMC 6, with a Sissell lump port head, a Clifford intake with 3 45 DCOE Webers, a Lunati cam (don't remember the specs), Vertex mag, electric water and fuel pumps, Venolia pistons at 11:1 compression with SuperRod aluminum connecting rods.  Never had the engine dyno'd, but the 3200# car's best quarter mile time was 11.13, 121 mph.  I want to try and replicate as close as possible  the engine that we had back then but we don't intend to run it as hard as we did back then.  If I recall, we shifted at 6700 RPM and crankshafts would last about 20 passes before they would develop cracks.  Back then, my Dad had no problem pulling engines out of busses and trucks in the local salvage yards, but they are pretty hard to find today.  We did score a long block off of ebay, but trying to find a Clifford Weber intake is a little harder. I have hopes that folks on this message board can point me in the right direction to help us find what we need.  I was just a college student back then when I built the first engine and was learning as we went.  I am amazed at how much I still don't know.  I would appreciate any help or guidance that any of you may offer.  I am always willing to listen.

I did indeed run a GMC powered car at Bonneville in the late 70s. But not from back east. I must say that a Sissell Lump port head and Clifford/Weber intake sounds a lot more like 292 Chevy six parts than GMC stuff I had. At any rate, Have you tried the Inliners International site? You might have some luck there.

I agree with Rich. My Dad was the Wayne 12 port head guy back in the day. Your combination sounds like 292 Chevy to me. While 320"  is a long way from a GMC 302 block starting point it is even further from a 292. I would be interested in the bore/stroke combination.

Good luck,

It was a GMC 302...I was there and saw it run...bad Acura car. Set the NHRA record in J/G. Jim is being modest!

They call me the Butcher,

With all rights I have earned the name.  I'm not afraid to cut on a brand new piece to make it fit my needs.

I have been a drag racer for the past 24 years,  and I don't see that changing anytime soon.

I have an addiction to fast cars, and old iron.

I am good at buying cars,  and can never seem to sell anything.

Now, Apparently I am that guy,  I joined your forum to sell some parts. 

I'm a drag racer that bought a LSR chassis.
I have no use for the wheels that are on the car.

For sale area, said to introduce myself first.  I will make a donation if I can make a deal.


I'm just a drag racer that bought a LSR chassis.
