I am seeking a roller cam block that I can put in a carbureted pickup. I believe that the rollers came out in 87, but by then GM was no longer using carbs.

Is this true? Crate motors seem to have both, so what else does? Any help is appreciated - THANKS !!!!!!!!!!

 

87 blocks had fuel pump provision and all 87-up were rollers. Not sure when they discontinued the fuel pump boss; had to be in the '90's.

A lot of crate motors won't "work with" fuel pumps because of the cam, not the block.

 

Truck engines used roller cams and mechinacial fuel pumps till 95

 

I had a 91 siverado and it had an electric fuel pump. My brother had an 87 and it came with an electric pump also. I don't know if there was a plate for a mechanical pump or not though.

 

On an 87 truck block, there was a blockoff plate. I grabbed the blockoff plate to use on my L69 when I added TPI.

 

I just got a ZZ4 cam leftover from a FB-385 crate motor (and it's for sale in the Classifieds!!) and it has a fuel pump lobe.

 

My iroc is an 87 and it has a roller motor and a carb (LG4 305)
