I was wanting to run roller everything. Should i run that same set up i.e. cam size and rods?

once again thanks for the advice

yep on e bay sounds abit over rated ? 690 HP?? i would build you a HYD roller cam engine with all new parts with a good 454 core block all fresh machine work .but less i see it come off the dyno. i do not rate my HP and TQ that hi and if you put it on a dyno and it makes more then what i sold you at the end of the day i not a SOB i would build it with H beam rods not stocker for the money . i can build a better engine with better parts and i may split the cost of the real dyno session with real numbers of your real engine
