im having issues finding a HV oil pump. im not lookin to spend a ton of money on it but i think it would be a good thing to have with the motor apart. can you post the summit link too

also my timing set is completely shot. i can almost touch the chains together its so loose. what should i get? and what does it mean when it says "use with 1 piece/2piece fuel pump eccentrics"?
also i have a comp cam xe270hr-14 cam. do i need something with more ability to be degreed such as this timing set

M68HV I think is the pn for a Melling 302 high volume, that's what I'm running. And I went with a Comp timing set, double roller pre stretched chain, 3 keyway index. And I just installed the cam straight up.

The fuel pump eccentric is for the guys like me that run a mechanical fuel pump. There's an off center "wheel" on the cam gear that turns with the gear and as it "wobbles" around it works the fuel pump arm. Ford had 2 styles, a 1 piece, and the more preferred 2 piece, but if you're running an electric fuel pump, like with EFI, then you won't be needing the eccentric.

thanks for the info on the pump eccentrics.

is there really a difference between teh summit chain and comp chain?

If Summit has theirs made in some crap factory in China and the Comp one is higher quality, then yes. But I have no idea where Summit makes their sets at. Timing sets are cheap enough that you can get a good one from Comp, Cloyes etc and not have to worry. Timing chain failure in a performance engine means valves go into the pistons, and maybe bent rods as well.

well i just decided to go with the comp one. the pricing was negligable and the description the comp one says pre stretched chain.

i did find the oil pump but im having a hell of a time finding a hardend oil pump shaft.

would this be the correct product?

Don't worry about Summit chain sets. They are Crane and are quite good quality. If you really want to virtually get rid of timing chain stretch. Take the chain and put in in a pan of oil and heat it up to 200 degrees for about an hour. When you pull it out 50,000 miles later it will still be about as tight as new. I never skip this step on performance engines.

never heard of that but great to know. thanks port. is there any increased chance by hardnening the steel that it may shatter?
