I posted a question in hobby stock forums and i am also going to post an engine question for you ford guys (hopefully im not the only one)

I am planning on running a hobby stock car in 05 or late 04 and my friend has a 1963 ford 260 v8 in his junkyard

my question is.. is the 260 worth re-building and hopping up or should i run the 260 heads on a 302 block..(i have a good 1974 302 einge with a warped head)

the rules say no porting but i do not see that they have any way to check that???... so sending the heads off to EXTRUDE HONE.. for some major flow work would not be out of the question..

rules limit you to a stock type 2 barrel carb (no 500 holleys) but say that the carb can be modified...) a 4 barrel intake with adapter is allowed.. so an extrude honed intake would also flow well

right now im just putting parts aside and doing some planning and taking all the advice i can get

so any advice would be appreciated

how much r's can you get out of a sb ford with a mostly stock bottem end and a non roller cam and no roller rockers???

also how much compression can one handle using 110 octane race gas???

any tips would be appreciated

thx
David

260 is way to small and the 302 may be ok but i would go with a 351 windsor myself with a good set of heads.

A guy at the track toasted his 396 and put a 260 together and said it suffered big time from lack of low end.I run a 347 with good results but it cost some bucks.It would be cheaper to go the 351w route. the 351 w would be cheaper if your going to do heads cam and carb.But I like my 347 its lighter than a 351 and theres plenty of blocks around,but there is more machine work to do on the 347.I thought about going the 393 next year but will stay with the 347.

thanx for the information

any kind of stroker would be illegal per track rules.... maximum cid is 360 for ford or chevy and 370 for chrysler..

so maybe a 351w would be the way to go..

rules do limit you to flattop pistons though and i want as much compression as possible because racing gas is allowed...

you can get the compression up to 15 to 1 with the ford n head and a flat top piston

dump the 260 take a 302 deck the block .010
take a set of 351 w heads 69-74 they have 1.84 intake and 1.54 exhaust and 60 cc chambers mill them .010 and that will jump your comp and will help on comp braking in the corners and when you get squirly in the straits just letting of the gas a little and you will get her back strait use forged pistons and ballance lower end you will be happy comp will be 11-12 to 1 depending on deck height and bore .030 or .060 and pistons
use flat tops

10:1 is all you're going to get out of a 302 with flat tops and stock heads. that's at zero deck, with .042" gasket and early 289 heads. cc'd one once and it came out to 9.9:1.
