Will a 5.0 e303 H.O cam work in my non h.o block and what do I need to change to run this cam with my 89 non h.o block ?? Need help by morning thanks!!!
It has e303 it's a carb motor I got it runningI ran a f cam in a non ho block and the intake valve just barely touched the pistons. Check piston to valve clearence and use the ho firing order but honestly it will depend on your compression ratio if you get any hp increase
I just ran with a carb it ran fine no backfiring or anything just swapped plug wires around advanced it a littleAh...forgot about the ole batch fire injection systems.
OP, care to provide more info on what you have and what you are attempting to do?
What did you put it in and what were you expecting?I put the cam in which was 351 firing order or "H.O" e303 cam gt40 heads and no valve clearance issues at all flat top no relief pistons stock lifters and rods 1.6 roller rockers block is a 89 crown vic roller block the motor runs great got 650cfm DP sounds good just not what I was expecting out of the heads
It's in a 89 gt mustang I thought the heads had a little more than what everyone made them out to be I learned the hard way I guessWhat did you put it in and what were you expecting?
Alright well thank you!I've seen guys get up to 300 rwhp with the GT40/GT40Ps. Requires a host of supporting mods. there are a few threads on combos with Dino numbers of you search around
GT40 cobra heads And 650cfm holleynon HO heads, intake and carb or EFI and an E cam? Uh no
