Re: What is Power Difference Betwwen a 393 and 408 stroker

if there is i cant see it being a great amount doesnt the saying go that you should be able to achieve 1hp per cubic inch from most v8s with ease. So an extra 15hp im running the 408 eagle stroker kit but with arias forged pistons alot of people said that the crank or the block it self wouldnt handle the stroke??? or something like that and that it would be doughy or sluggish, i didnt find any of this to be true havent had any problems and i think for the small camshaft and low compression the figures and E.T. speaks for itself. Good Luck

I'll take a FREE 15 HP anyday. Wouldn't you? And before anyone says
it makes the block weak, go and ask on the 335 Forum, as there are
many guys racing them hard, and i havn't heard of one single failure.
408 all the way in my opinion.

15hp when you average 408 will do 450+hp at the rear tyres is sfa prob a 0.01 over a 1/4 at best. I do agree though. 15hp is 15hp.

Many of the failures on the 335 forums were shall we leave it at "error in judgement?" There's plenty of 393/408's happening. Myself inc eventually.

For what I'm doing on the next engine that's achievable. Even though I said I'm not stressed about the power level but the torque has to be through the roof. I'll be having a camshaft matched to the head flow this time round. I stated I wanted the car to run 10's and be sedate enough to drive on the street. Sedate in my definition is my current combo is sedate. Should be fun when it all happens.

I'm sure I'll be at Calder enough once it's done. For the moment the 351 gets raced while funds build. Once the fund are there new engine starts, the 351 short motor gets a rebuild, sold off to pay some of the costs of the new engine
