heres the restrictions:

1. 6000 RPM
2. 93 Octane
3. No meth or NOS
4. 34 degrees max timing

N/A or forced induction? Probable cheaper to go with a 454 with a whipple than to build a 598 or 632ci N/A motor.

I don't know if it's the cheapest or not, but I have big CI N/A engines in my boat that are making that. Dart tall decks, Callies cranks, Oliver billet rods, J&E pistons, AFR cnc heads,Morel hydraulic rollers, they idle great and after 140 hours have been trouble-free....Knocking on my wooden desk as I type this!!! A leakdown was just done a few weeks ago and all is very good. I have them propped to run WOT at 5800-6000. They made 803HP @ 5900

whatever floats your boat just include some estimated costs........

nice set up oldschool. lets get some prices up and start debating..........

Just for fun, Round up wild Mustangs. lol !

Find someone that has one already built to those specs. Waiting for his dream boat to come along. Then he loses his job, needs to make his mortgage payment before the bank repos his house and kicks him, his wife and 4 children out on the street. Then give him a call.

Cheap and 800 hp, don't know if that works

Cheap, Reliable, Fast(Big HP)..... you can ONLY pick two and you WON'T have the third.

i know what ur sayin jms322, but im just saying in general....i saying cheapest as in production parts, no crazy custom parts etc.....and also blowers or na??? what cubic inch, what blowers (if any), etc....
