so i take it no one here knows the best mods to do in steps ??

stroke it,,,,,,,,,,,,,,,,,,,,,,lotsa $$$$$ involved

[rorrie]

ok say i only have a couple of grand to spend sorry i should have been more specific i guess

[blo304]

Buy a 3500 stall and spend the remainder on the trans honestly the best thing you could do.. cam only will give you at best 20rwkw or touch more

id go with a cam, and get the heads shaved 30thou to boost compression a bit, depending what size cam you go a stall may be needed also

[rorrie]

ok cheers mate what do you reckon that would all cost. and if i was to go with the cam as i like the sound of them what would be my best option. what im trying to do is build my car in steps as my wife won't let me spend all our money on it. its my daily and iv'e heard cams can make it a pig to drive but thats coming from people that have never done this sort of thing. cheers Rorrie

Here you go,

Stock 304, Guide to choosing a camshaft

People are on the money for cam and head shave for the cheap. I dont have a clue about auto's and crap so im usless there

Will you do these mods yourself?

[HSV557]

Is there a cam guide anywhere for the Harrop Stroker? Or some general info?

the stories you've heard about cammed engines being pigs moreso refer to the old carbed engine days.

the EFI 304 isn't going to be a pig with a mild to moderate cam
I've got a moderate sort of cam in my 304, and it's not much different to drive around town than a stock engine. Gets a little cranky (manual transmission) if I'm crawling along, clutch out, walking pace in traffic, but that's more to do with the 3.08 diff ratio being a bit tall for the cam.

much of the driveability of a cammed EFI engine comes down to choosing the right camshaft for the combination you have & the quality of the tune
Keep in mind with your budget, that a good tune is going to cost around $1000 (but it's a once off cost)

go the hi stall mines got 3000 in it and made a huge difference .ive got 4.11s aswell polish your throttle body to a mirror finish theres a gain to be made there mine looked like someone had shit in it polished heaps better.advance ya timing to 14degrees make it more pokey of the mark best of all these cost nothing to do . try and get some nice cold air into it. good luck with it.

ok so if i go with a moderate cam and shave the heads 30thou what would yous say this should all cost? i will not be doing any of the work my self as shes my daily. with the stally do i really have to have one id probly take her down the 1/4 once. cheers guys for the info and could yous suggest me the brands sizes etc
