DeTomaso Mailing List: May 99, Message #204

dean,

thanks for the detailed reply.  i'm also gonna use the intake port tongues & exh
port plates - but i thought the intake plates went into the heads, not the
intake - i'm using the 4v quench heads, not the 2v quench heads, tho... any
difference here?  also, you dint feel compelled to screw the tongues in as well
as epoxy 'em?

thanks again,

doug

	Subject:	Re: blue thunder manifold exp.

	dear doug,        i did not purchase the blue thunder from m.a.p.(MARINO
PINA)
	   i think i have his last name right, i tried to but he was out at the 
	time,so i got the reportably new(USED) manifold west of the
mississippi,but 
	not west of the rockies i would prefer not to get any more  detailed as
to 
	the vendor as i may be forced to get something more there.    as for the
help 
	i have recieved from marino at m.a.p. he has helped me greatly, as it
turned 
	out we took his advise in building the motor, do not have it in car or 
	running yet but he says it is close to the way he built one of his
engines 
	and it has worked out great for him.  we tryed the port plates, marino
sells 
	them,but discovered after looking at them they seem like a sealing
nightmare, 
	so i took his advise and purchased the alum. tongue's he sells.
after 
	some filing and die grinding the tongue's were j.b.welded(STEEL STRONG
EPOXY) 
	inside the blue thunder and them after drying the tounges and manifold
were 
	given a die grinding to smoth out the transition.  i went with a pair of

	"quenced heads" with smaller ports so there was some work inking the
manifold 
	and heads  to make shure all transitions from 2v heads to 4v manifold
with 
	tounges in place were SMOOTH. this type of setup is supposed to improve
low 
	end faults in the HUGE ports in the 4v heads.  we allso milled the deck
and 
	heads to a tolerence of somewhere around 40 thousands ??? i may have
this 
	number wrong , marino can help with this,and am running forged TRW flat
top 
	pistons.   this combination leads to a lot of squeeze(compression) but
the 
	small chambers and tight head/deck clearance is suppost to eliminate the

	areas where detonation can happen, meaning the beast should run on other
than 
	super high octaine.      i have purchased other items from m.a.p all to
my 
	satisfaction . as a side to this, since i had a total redo on my hands
and 
	not wanting to do this again, i have replaced just about every damn
thing i 
	can, including any sheet metal that may be marginal(i live in the great
white 
	north where every thing turns to rust) since i could see evidence of
some 
	rust under  one rocker panel that  to me said replace them both, after 
	hearing storys from fellow owners as to the poor quality of the
aftermarket 
	pieces.  the rocker i got from marino were correct in all the bends and 
	curves in both directions. they were a tough instalation,however we were
able 
	to install them as to need only small  spots of filler to fix mostly
damage 
	that happened in shipping                           good luck
	                                      hope i did not ramble on
