any advice on what to do for stonger frame so dont twist and front suspenson to handle the waight from a v6 to 351w thx

 

kilometers? oook, i see your from canada, i dont know what 145km converts into miles. i did not know NOS is illegal in canada. anyway. what kind of car do you have? depending on the year you might have to do some work too the engine bay before you drop that 351 in. for a stronger frame, subframe connectors are good. you will have to upgrade the suspension, also the rear end and transmission to name a few others. look around in the FAQs for more info. there at the top of this forum list, not at the very top near the logo.

 

ya it 1986 ford mustang lx my dad said i should be able to drop my 351 in there np but do u know what i can do to change it from lots of pulling power over to high performance like cams and stuff

 

1986[8D] thats old but not quite to classic status yet. ask your question here https://mustangforums.com/forumid_14/tt.htm , they can help you more

EDIT: or did you mean 1968 and not 1986?

 

thx i meant 1986

 

ok then, the 5.0 guys will be of more help.

 

the absolute biggest problem with stock 351's is the garbage cylinder head, you will be hard pressed to make any signifigant increase in power with that head. The most economical thing you can do is one of two things. Find a set of old D0OE heads or use a gt40 302 head and drill the bolt hole to 1/2 inch since 302's use a 7 1/6 head bolt. Thats what I would save my pennies for. Then you can step up the cam a bit, until then your not going anywhere

 

I agree 90%. The heads have to go.
But the GT-40s and most aftermarket heads already have the 1/2" bolt holes. No reaming required.
I installed TFS heads on my 351W with a mild cam. Needless to say, I was quite happy until the clutch disc ripped apart.
