It will suprise you ,
My best wild guess would 460 rwhp 450 tq

That low?

What would be the cause of the low numbers?

why the 72cc heads??

what is your final compression gonna be?

iTrader: (1)

Compression ,intake manifold ,78 mm throttle body
Those heads a fast manifold and 90 mm throttle body
11 to 1 compression and you should be close to 500-500

that's a small cam also.
cam, compression, intake, manifold and throttle body is something that will make a big impact on hp number.

Well one thing at a time lol. The cam is just a starting point got to see what i like for the street. Which this is a daily driver I was told with the 72cc chamber and -4cc pistons and all the final CR would be just over 11 to 1, which after assembly I turned it over without the plugs to check all my valve clearances and it was nice a tight and pumped air very nicely, then installed the plugs and the thing had major tightness nice compression build up haha. I reused the afrs from my last build which was FI but figured theyd work good.

I do not plan on staying with the intake and TB combo for long I have a harrop on order just have a while to wait till it gets here. Well that is if there was enough on my credit card, ill know tomarrow haha. If not I will install a ported fast 90/90.

I am interested in all the 427ci results posted - they seem to be as varied across the board as all the various possible combos out there.

I would have hoped a 427ci LS7, LS7 heads, nasty cam combo would be closer to 600rwhp than 500.
