What do you think?

Looking to see what you guys think my engine is putting down for power. Here are some specs for the engine let me know if you need anything else.

F block j Heads
Comp Cams extreme energy cam----- grind number XR290HR
Edelbrock Air gap intake,
Holley 600 street/strip carb------80457-7
Hooker Supercomp headers,
Roller tip rockers, Hardened push rods------ comp cam


I know it needs a bigger carb but not sure exactly to put on it..... I also know that the j heads are a big down fall from what i have read. Ive heard C heads are way better, but what do you guys think?

You can download a cam selection program off of comp cams website. This program will show you what kind of HP you are making with a comp cam. It is one you download, not the flash type one they have. It is called camquest. You can even input your own head flow numbers. I am sure it is optimistic since they are using it to sell their cams but it has to be ball park atleast.

Also large valve C heads are about the best factory heads you can get.

edelbrock heads, best bang for your buck right there. I would throw a 750 cfm holley on it, i dont think a 600 is good enough.

would the mechanical fuel pump beable to keep up?

Is the pump stock oem? or aftermarket? I'm not sure to be honest but if you ever need a high flow fuel pump then there's many oldsmobile performance places that sell them. I have a 150 GPH mechanical pump that i bought for $30 off ebay, works great and has great fuel pressure.

well it doesn't look stock havn't really checked out the fuel system yet. only thing i can tell is that there is one inlet and two outlets, i think.
