I have a 502 short block so far and I am looking for a good combo.The short block is basicly a 502 mag bottom end.I was thinking of running WP merlin 310cc 225 188 heads,Crane 113971cam226/236dur.@50 587/610 lift with a 112 cl,850cfm holleyDP with a ? for a intake(Single or dual plane).The only thing I will not have this year is good exhaust.Is this cam and heads too big for stock exhaust ?I want to try to get a happy medium where I can build the engine to where I can run stock exhaust this year and make good with better exhaust next year without doing any changes(.Looking for the best bang for the buck)
Thanks

Check that cam # and re-post. Make sure you look at the specs of the one you posted

I calculate 478 H.P,502 Torque @ 5000 rpm WITH Stock exh. and single plane intake, 8.75 comp.,hope this is close.

I can't say anything bad thats the cam I'm installing in my motors Couple more weeks and I'll have a answer.

BTW HP500 carbs a lot of head work and a tad bit more compression.

253 Thanks
What program for the dyno?Scott, do you think this cam is to aggessive for stock manifolds?Let me no how you make out .
Thanks
Dave

I will post all my results when I'm finished. Sorry I can't answer your question about the stock manifolds. If you plan on replacing them next year it may be a logical choice. I guess the worst thing is that it could be some what restricted till the change over. Scott
