I have a 4.5 stoke 55 over 440 = about 540"
It has std port cleaned up VICTOR heads 10.5 to compression
victor intake manifold (soon have Holley EFI (HOLLEY HP) ) waiting on a few parts to arrive.- 1000 cfm throttle body at big injectors.
Full length 2" x 2 1/8" step headers
4 speed
dana 60 w/ 4.10s and 31 x 12.5 et streets

CAM IS ALL WRONG- it is 680 lift, and 287 duration @ 50. Solid roller
It comes on at 5k and pulls way too hard - for street use.


I want this engine to last for a while, i dont want to throw the rods out the side of the block so i need to make less power at less RPMS it also needs to have better manners on the street.

What would be a good cam choice for this motor that doesnt just crush the HP level?
It will see lots of street miles.

If you're still thinking you might run E85 I would raise the compression.

Where do you want it to make peak power?

For that much displacement I would run a 4500 over a 4150 throttle body.

Retard the cam.. might take a couple of changes

Isn't it "advance" the cam for lower RPM power and retard it for higher RPM power?

Thanks, but I am trying to go the other way with power. LOL, i want less power for the street.

so i need to make less power at less RPMS it also needs to have better manners on the street. What would be a good cam choice for this motor that doesnt just crush the HP level?

Try having that cam reground by Bullett for your street use
I'm thinking around 245 to 260 @.050 with as much lobe lift you can get on a 108 LSA installed around 104 ILC
