My Muscle Truck

Here is a before and after of the engine bay in my 1972 GMC 1/2 ton Pro-street truck.

Before


After


Here is a vid of the 3rd time I started it with open headers... you can really hear the cam. It's gonna be a ground poundin' Mutha...

Edit: tried to imbed, but for some reason it won't do it...

It's almost ready for the road... just a few more things need to be done. Can't wait.

Love that sound!!! Gets me all gristled up!

My favorite body style . Sounds good GASoline71.

Deeply sadden'd by the none Big Block in there.....opcorn:

Sounds like a runner to me. Nice.

Those old Rams-Horn exhaust manifolds flow more then some give credit, no headers, but they can flow well.

What grind cam you running now?



I am running a 73 service truck now, you really get away with a lot when it comes to emissions-testing.

Gas mileage? We don't need no stink'n Gas mileage.

Sounds good!!!

Get an old-skool engine to flow, keep your foot out of it, and you would be superized the millage you get.

The trick, keeping your foot out, RV cams are fantastic energy cams!

Comp Cams... 280H

Steve... no cash flow for the big block. Plus this Mouse will eat a lot of big blocks... trust me.

Gary I guess I was spoiled with my 540 in the early 90's....

From the hip,,,, Dart heads?

I spent way too much time at the track over the years,,,, but stihl can not make out the heads here, some spy I would be?

74cc 2.02" intakes , Dee-shaped? Maybe lowered and reworked?

Yep... had some work done to them... they have the stock 210cc intake runners too...



Gary

Hmmmm... that looks like a cruise control on the fender in the old pic.

We need to see the rest of the truck too?

That is the stock dealer installed cruise control. I just reinstalled it yesterday. It works, but not so great with this engine... not enough vacuum.

Just my $0.02 cents worth,
No, a 280H grind will really start to produce power above 2500 RPM's , and will have a very choppy idle. With very little vacuum.

Comp is about number 1 around here for strip and street/off-road cams.

I could recommend any of these 3 cams for a non-strip 4X or wood hauler!

XE250H


XE256H


XE262H

If you want vacuum accessories to work well, but still a little power to play with.
