That sounds mean. Who is going to do the build for you? Did you ever get any resolution with your warranty company?

Daniel Hoffele

Yah it should be around 600rwhp and a**load of torque...yep got 10k from the warranty company just enough to cover the short block

Injector Dynamics 725's for the injectors.

I'd rather use a RHS high port cylinder head and get them professionally ported. Only raised port LS7 head on the market that's a true bolt on for the fast intake.

Daniel Hoffele

Heard good things about those injectors not sure what my build has got for the motor yet thou.
I looked at those heads but at almost 2k more than the mast heads I can't see them being worth that for .2" raised intake port but then again never used them or see any test the the rhs vs mast
As for as the fast intake my god did it need a lot of work. I have about 30hrs into that intake for something that cost that much is nuts. Just were the runners met the bottom of the intake took for ever to get them to match some of the runners were 1/8 smaller than the bottom intake

That is a super great build! It'is going to be a monster!

2K more than MAST's?! What masts are you getting and what RHS heads were you looking at?

Mopar Jimmy

Very cool, how exciting for you, best of luck, will be a MONSTER with great heads too!

Spec C

Was wondering the same thing. RHS Heads are like $3650 fully cnc ported by Frankenstein.

had the valves mixed up mixed up so yah that adds alot of cost for sure
Dont think ill ever go to titanium valves thou since both my intake and exhaust valve guides were worn at 49k mile the exhaust of coruse were way out of spec

Daniel Hoffele
