So a rod bearing went after autocross last weekend. This winter im planning on doing a 355 with a stock crank, H beam rods and (i think it was) speed pro pistons. My heads are gasket matched so i was going to buy this cam off my brother and he said he thinks the lift was around .580-.590. Then ill buy some stronger pushrods and swith the 1.6rr comp magnums for some comp magnum rs. Im in the process of installing a 4.10, adj lcas and panhard bar, and a lighter flywheel. I have full bolt ons, a 58 mm tb, cai, pacesetter longtubes, a y pipe, and a 3 in cat back. Anyone have any comments or suggestions, or an idea of the kind of horsepower ill make?

 

Or even go for a bigger cam?

 

Stock heads ? That plenty big

 

They have been gasket matched

 

Gasket match does nothing. So I have heard...
if this makes sense...
/ \. Intake
\ / head

 

Yes ive heard of that too. But they already are so big deal ill live

 

They were opened up as far as the bit would go. Idk if thats what everyone was still thinking or not

But enough about the heads...

 

Sorry about all the posts but im on my phone and cant edit them... Also my goal is mid 12s or better, and for my motor not to break after a lot of autocross! Are these goals realistic?

 

Goals are absolutely realistic, with that big of a cam and some good driving you should see 11s.

 

I'd guess 340-350 rwhp if tuned properly.

 

I have the cc503 in my car now. Ive heard that is the biggest cam you want to go on stock heads. Is this entirely true? I know mine are just gasket matched so i dont really know how much better they flow if any at all. But i am pretty set on buying a bigger cam like i stated above. Im just trying to go as fast as i can with a 355 and cam. Any objections or suggestions?

 

Oh and the cam i want to buy off my brother is a comp. I think its an xfi if that helps. I wont know exactly what it is until he pulls it out.
