I have the mild Mopar Performance cam in my engine. Works well! I have the Renix EFI system, but using a 99 intake with a Renix bored out throttle body on it and larger Ford 5.0L injectors.

I replaced the fuel line in my gremlin for 2 reasons, first because the fuel was on the wrong side of the car after upgrading from the 6 to the 401, and second because the fuel line was 45yo steel. used bendable 5/16 aluminium from summit racing.

True Rebel Bob. Volumetric efficiency. Id love to have ducted pre radiateor air intake. This also allows for more timing and quashes detonation. Id love anyones ideas of what parts to use to do this...its free power!

Cool thanks,
My car sat for 13 years. I imagine there is rust (artherio sclerosis) slowing/constricting fuel to some degree. i wish the holley 390 had an adjustable rear fuel block. I did drill the stock fuel block with success allowing for super lean cruise and some compensation to enrichen fuel to rear barrels at WOT. Can someone chime in as to who makes a performance fuel pump.. Tnx |
