hello, i need some advice regarding a 98 cobra


i am building it up for american iron, road racing action, and it needs to remain Naturally Aspirated.
i need about 350 rwhp, and 360 tq, which will give me just a little wiggle room, depending on her final weight after the cage, and all.

i think i want to do some b heads with port/polish/valve job, and cams.
looking for advice.

the car will NEVER see forced induction
it may, down the road get a built short block with higher CR, and stroker crank (+/- on this),
maybe never, if the heads/cam/intake get me where i need.

what do i need to get and do. to reach my goal
i am looking to maximize are under the curves, not for peak numbers.
i want a long flat torque curve, and to be able to use as much rpm band as possible.
this will be a strictly road-course racing car.


does it matter what 4v head i start with???
cobra vs Lincoln Mark VII, vs (do navigators come with some DOHC / cobra-compatible heads?)
how much of a P/P? i don't want to go too wild, and take a step backwards, considering i wont be adding FI

should i even port em at all, and just do cams?



oh yeah, where are we right are now:

stock power plant with :
LTHs, off road h pipe, and flomasters with dumps/turn downs
smog pump/egr delete,
a K&N filter,
and steeda 10% UDPs, and an aluminum DS,

yielded a disappointing 287/283.
not sure how much he left on the table, if any


thanks,
doc

i DID just read the sticky, about heads
wow,
a lot of info, and things to consider.

in the 1st part of my post, i indicate i had been planning on staying with B heads, since that is what the car has,
and by doing so i dont have to switch from a return to a returnless system (or di i have that backwards?)

now, having read the sticky,
i am even more confused as to what will be the easiest/cheapest to reach my hp/tq goals, naturally aspirated,

doc

 

Are you a member of the Corral or SVTP? If so find a member that goes by "na svt"
He will have good info for you and it will be correct. He knows his stuff

 

Well I guess that answers that question I just went over to the Corral and see you posted the exact thread there. I'm sure he will jump in on your thread

 

Honestly, it's going to be difficult to reach those numbers AND have a flat curve. Those numbers are attainable with head work and some large cams, but low end torque will suffer...

Just throw an ls1 with bolt-ons, and you'll be right where you want to be, with no headwork! lol

 

He said he was building and AI car so he can't do a LSx swap

 

I was being facetious...

 

and i was f'n with you
