hi dude, it takes big cohones to attempt this modd , so well done...
where abouts did you get the "trumpets" and plenum shape........ $$$$$
what are you doing to your box to survive this + turbo....??
\
why not go the twincam head?? / motor....? sounds like you want to go all out.
or is the 12valve head good for the numbers...
velocity stacks will be from
www.velocity-of-sound.com, plenum extrusion from
www.rossmachineracing.com.
gearbox, i have a spare that will be rebuilt and all of its internals cryo treated for increased strength and wear resistance. it may get straight cut gears for 1st to 4th.
i was going to go dohc, but then it would have cost me about $2k including the purchase price of the head to build the head to how i want it.
i have 2 sohc heads, and i firmly believe that they are capable of pulling big numbers. some drag racers in puerto rico use the sohc as they are lighter than the dohc, rebello racing uses sohc KA's in their off road racing trucks which are pulling around the 300hp at the flywheel in NA form.
I did my own solid lifters for the sohc head (as well as noss's). When the bottom end is built, the engine will be good for around 7-7500rpm, if not 8000.
and yes he has guts to do this..
it's too late now mate, i've already got 50% of the parts and my forged pistons were ordered yesterday.
