What's with all the CAPITAL letters? And please try to use some sort of punctuation in your sentences. I can't read this. Don't know where 1 sentence starts or ends.

With the fuelie heads(I think thats what you meant)400 rear wheel hp is pretty dang good any more is probably going to require a head swap.The cam if I read the numbers correctly is caspable of 500 to 550 fly wheel hp.

yea sorry it was 240 kilowatts at rear wheels,(im unsure of hp not sure of right conversion) with lots of slipping thru (converter or tranny),do you think the 210 afr cnc heads and rollercam will ad a great deal of hp.Also ive just bought full msd ignition 6al etc..hoping maybe bit of difference and maybe looking at getting 750 or 850 mechanical carb thanks. :sweat:
