Wonder how these would hold up

Yeah, I've been thinking about one of those too. FBC, are you using one of the higher quality bronze tipped pushrods? I have read quite a bit about the cheap ones wearing down quickly. I too am concerned about the heavy spring in this pump. I guess that is to keep the rod following the fuel pump lobe at high RPM. I don't want this to turn into an annual headache because it is very hard to get to the fuel pump on my engine when it's in the boat.

I have one of those and got scared to put it in. I was thinking if the end would mushroom out I might not ever get it out with the engine in the boat. The ones I am using now are comp cams #4607.

I had a buddy run one of those comp cams brass tipped ones with a flat tappet cam. He mushroomed it after a couple hours run time and couldn't get it out. So he installed an electric pump. :-(

I have the Comp part to use in this engine. I've used them in other builds without a failure. Perhaps something else caused it to go south? Why use a brass-tipped pushrod with a flat tappet iron cam?

Good Thread! Been wondering what to use here? I like the Specs on that Baker Pump! I havnt used Mechanical pumps in 25 years! Want to put the BEST one in right from the start! I might be wrong....doesn't "CrashCar" have to run Mechanical pumps? If so...what are they using? Baker puts out some NICE stuff...do they offer a pushrod?

Comp said they work with either cam. Obviously not!

Guess not!!

What about the GM Performance one for use with their steel billet roller cams.

ARP makes some GREAT Products....do they offer?
