Hey guys i'm new here but was hoping i could get some advice about a 454 i'm building. Its a 91 mark v (gen v) block. I was hoping to reach a "street friendly" 600 hp and around 650 trq. What advice does anyone have to help me reach this? Also has anybody heard of procomp or patriot aluminum heads?
much thanks-Steve
600 HP WITH WHAT PUMP FUEL? for starters 600 hp is abit i would put a 4.250 crank in it would make less work and less rpms to get your numbers what your ideal of street friendly?????Quote:

thanks-steve
well 600 hp is abit much with out a power adder and good street manners with 91 octane but 500 tq is not. you will feel that a 496 is a 454 060 over and 4.250 crank if you want more hp and tq your looking at alot$$$ and bigger every thing i know how to do it with no power adders and race fuel hi ch and a nasty solid roller cam with the 454Quote:

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:3dSMILE: 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 engineQuote:
