Some of you that have done builds do you think this is possible?

I guess thats a no.

I guess thats a no.
400RWHP = 450? at the flywheel
There are guys out there with well built, cammed 383's with aftermarket 195 cc heads that are touching 400RWHP
Pushing @#*& uphill with the little 160cc 113 heads

That would be a stretch for sure.

No, that is why most that do a build won't even look at them.:kngt:

are 113 heads capable of 400 to the wheels


Can be done with $$$
383 .Extrude honed and fully ported heads aftermarket intake , $1500 fuel management system 458 FWHP

The only reason for going down this path is to keep a stock(ish ) appearing engine.
Extruding honing is expensive; like $1075 for a set of heads plus porting costsand you notice no pricing on the head work is given in the writeup
Sure to be able to buy same or better performing aftermarket head for less $$$

Ultimately is it going to be worth putting the money into it to make that power?

I have always thought of those heads as a weak set up, just from seeing what has been done with them.
