Hi i got a 351 windsor for free from my grandpa it only has 145,+/- km but it outa 87 ford F-250 i need some help on just how i can get performance and fuel econmy. i want to know what i can put in it for a good camshaft one prob i dont kno how to get the compression ratio and then what else i could do to add power fairly reasonly priced other then NOS where i live it illegal but and help on telling me what i could make it push for RPM's i need as much as possible and one thing r the 351w and 351c tranmission bolt up patteren to the block the same.
any advice on what to do for stonger frame so dont twist and front suspenson to handle the waight from a v6 to 351w
by the way i wanna make it red line around 6500rpm's but im not sure of what all i have to do so ny help thx

 

redline is about 6,000rpm so worries there.

351W and 351C are different and will not bolt up the same

351W has more in common with the 5.0L 302's

351W will bolt up to any 5.0L trans., as far as your late model
V6 you will probably need a new trans. T-5's with super alloy gears run about $900

Good set of heads and cam and such will get you 400+hp at the crank or about 325+/-rwhp
stock 351W made about 275hp at the crank

you can also stroke it out later to 408

so id be best to find a 5.0L tranny 5-speed what r they c-5's

 

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

 

auto is called a C-4 i think

manual is a T-5 or TKO-500 or T-56 6speed.

Get a 5 speed, imo

so stock heads to make any hp is usless

 

yes the stock head is going to get you nowhere fast

 

remember you can use most any head for 5.0L by drilling out the mounting holes
like Shifter said.

 

ok alil bacground info it was 1986 mustang lx came with a 3.8l but i wanna put some power in it the only prob was that where i live i cant find 5.ol in wrekers or on the side of the road and i got given a 351w and mounts will the trunk mounts mount o my frame

 

You will probably need 5.0 motor mounts.
