Cam Package - 420WHP N/A SBE LS1 98ULP 

@@robmotown1 yeh would be a good idea. Lots of things I would like yo do with the store if I had a little more time! Too bloody busy to do anything its extremely frustrating.

The issue you begin to have by going much bigger is bleeding too much dynamic compression due to overlapping valve events. Generally when building a pretty wild combo with a really big cam you combat this with more static compression. With the stock pistons there is only so much compression to work with though, we have found this cam to be a very good balance getting good results with stock compression and still not requiring any fly cutting for pistons to valve clearance. If this combo had a solid single plane manifold and throttle body setup we would expect to net another 15-20whp, and that is just about the ceiling for a SBE 5.7

No you would need ported heads for that Cam for best results as well as an OTR.

Crow cam 1250

N/a?????

@@maxarndt8087 yeah mate have the dyno sheet to prove it?

@@grahamerosewarne6656 what is done to it that figure seems a bit high also you do get quite a bit of variation with dynos

@@johnboy5167 probably heads ,cam, compression, and a good intake. I’m at 443 bhp on the stock 853 heads

@@johnboy5167 will get the work off him and dyno sheet for you.👍

for sure mate, flick us an email info@onsongperformance.com
