BIG power, LOW weight?

Not a combination I would recommend unless you plan on tracking the car as much as street driving. However, it would be streetable to some degree.

There are easier ways to make the same power with a bit more low & mid range for a lot less money. For example, an aluminum 351 / 408, 10.5:1 cr, AFR heads, good hydraulic roller, and a 750 HP will easily make these numbers for thousands less. It would be more streetable as well.

Exotic is cool but does get expensive.

Good luck, John

I dont know if you have ever driven one of these car before but it does not take 600hp to move it down the road like a rocket.
400hp in a 2300lbs is like 600hp in a 3600lbs muscle car.
And with the short wheel base she will swap ends before you can say oh s%&*.
Will somone cut in and tell me they have 600hp that they are actually able to use all of it. HP not planted to the pavement is waisted.
I have about 450hp and getting it to stick and go is the hardest part.

I can hook it up in 4th pretty good.

Doesn't The Engine Shop here on Long Island offer an aluminum 351W based block? If I'm correct, the sky's the limit on power. 600 HP and up should be easy with one of these engines. The again, there's always the possibility of an all aluminum FE, with even more rediculous power potential. The big question is, how big is your budget?

I am running a 351 based 418 with dart alum heads... this weighs about 500 lbs w/o trans. I used the newer siamezed sportsman block... the alum block saves about 90 lbs but it will cost you. I think the 351 is a good compromise...

What is your bore and stroke on this engine? Was it dynoed? HP, torque?

It will be on the dyno next week... I am expecting 425 rwhp. Eagle forged 4340 crank and SRP Sportsman Racing Series pistons 30-over. Motor seems very strong and hits the 7k rev limiter hard... so far I am very pleased. Nitrous is going in this week and I will probably start with a 150-200 shot... if the car and driver can handle this I will bump it up maybe as far as 300..
