this is how i'd say to do it.

twin webers
full port and polished head
full exhaust
if its for street use about a 30/70 cam
shave head to get the comp up to 10.5 to 1,
rebuild the engine and get everthing balanced
also lighten the crank and fiywheel

thats my 2 cents

where are you ?

what about your coil and plugs

the block of wood wasn't that badder idea

does his aways happen ?
you could have just got some bad fuel

is this engine running big comp ?

dam that thing is low

good hunting datrat dave those utes are crazy.
I say take a look you won't be disappointed

I say 60hp at the wheels at 6000

Very nice indeed
Looks good and goes hard what more can you ask for

i've got 2 1/2 inch mandrel bent exhaust on an a12 it works fine.

if you get extractors put on.
don't get hitech ones they rub on the bellhousing
