Have a look at the link below. Do you guys think that combo will really do what they are claming??

coming from brodix... fact!!... best if you have any doubts, call brodix!

Is the stroke mentioned somewhere?

I dont doubt the output, especially if its a 383, and its more an ad for the expertise of the engine builder, he chose the components that he knew would work well together.

wonder what the intended use is... Race, street, boat,..????

Good build, no doubt. And yes, those power numbers are plenty "doable". Certain key information has been left out, though. I'd like to know the stroke, as well. I'd also like to know static compression ratio. With "staggered" rockers, the port work is also VERY important here. Unusual to have ported the exhaust "side" to be that much more efficient.

We've built many 383s over 500 HP, using Dart Pro-1 heads. Brodix heads are easily as good (or better, depending on WHO ports them).

I never liked the hydraulic rollers, though... Fine for stockers, but the REAL gains come with solids.

as mentioned, the stroke was left out and whether or not any head work was done is left out. since this was built professionally i would certainly think that they did clean up the heads etc. and if this is a 3.75" stroke then absolutley those numbers are achieveable. that is almost exactly what my 383 is putting, but mine doesn't like pump gas (11.2:1) i have to mix my fuels to run on the street. but they also mention a 112LSA which would help bleed off some of the cylinder pressure where i have a 106LSA which makes it harder to run pump gas.

if it a 3.48" stroke then i would have a little bit harder time believing those numbers with a compression that could run on pump gas.

Since the stroke was left out of the build, I was trying to look at the oil pan rails on the block and see if it looks like some material has been taking away for clearence of the 3.75 srtoke crank... its hard to tell, but looks like some material has been removed, so most likely it is a 383.. as for piston's since they are Mahle pistons, im sure they have a 4cc eye brows.. so figure a .040 quench then go from there..
