Cam Question for 5.0

[wickedbird]

I got the build sheet from JBA for the motor in my car and the cam seemed a little small. I am not sure what brand it is but it is a hyd roller with .480/.480 lift. Is it worth it changing to a F303 with .512 lift? What cams do you guys suggest?

remember if you change a cam your are going to have to measure piston to valve clearance.. Back in the days the largest cam without checking piston to valve clearance was the E-303 with a .498 lift...

So changing to a E303, is it worth it? My piston to deck clearance is .018.

what heads and what are the cc on them?

 

[wickedbird]

For some reason on the build sheet it didn't list the CC. It just listed 8.5:1 compression and they are Eldebrock heads.

No idea. When i get home in 3 months I will have to get the info off the heads to find out what I have.

All great questions Emilio. Bird, since the car engine is custom built, you will need more information before you can determine your max cam lift. If I were you, I would get all the information and take it to Cower Cam. Tell them you are looking for a custom cam and give them the information on the engine. Once they make a recomendation, use the information to buy an off-the-shelf cam that is affordable.

Thanks for the help with this. I am going to tear into it once I get back. Once I get that done I am going to take it back to JBA to get it re-tuned and dyno. I am hoping that with smaller pulley I installed and new cam I should be in the 420hp range.

I recommend you take it to RPMM to get it tuned and dyno. They did a much better tuning on mine then JBA did.

What did you end up spending if you don't mind me asking?

They had a special and it was $300 for the tune. I believe its $400 or $450 normally for the tune. Not positive, may want to call them to make sure.
