Why not a 351 Windsor in at GT40

[Jim]

I have noticed that most guys use a 302 based engine for their cars. Any reason why you wouldn't take advantage of the cubes a 351 offers? I know the headers would be affected. Fran, do you offer a modified set of snakes for a 351? I know you are reading this Fran.... Is authenticity the other main reason?

 

[Grant S]

no matter how authentic you make it, It's still a replica, go for the cube's 351 stroker 408, 427 have some fun, Kill some tires

Custom headers are available...but expensive...

stick with a 302 based engine...347's make plenty of power

NICE Bill :thumbsup:

Bill..looks great

but do you want to let Jim know what you paid for your headers...??

 

[Bill Cooke]

347 with a simple Holley 4 barrel: 450 HP 425 lb/ft torque. No special headers required and I can tune it.:happy:

 

[Jim]

Ok, how much? I can tell I'm going to be shocked! I ask because I have a 351 tucked away in my garage. How much HP can a G50 handle?

 

[Seymour Snerd]

I think it's safe to say that the vast majority of Superformance GT40s have 427 Windsors in them, almost all made by Roush.

G50 transaxles can handle 475-500 hp easily...the later ones will hold much more..my 6 speed unit in the 01 race car has taken 600hp of abuse on track with slicks without issue.
You can cal me or a quote on headers with you choice of ss or mild steel but there is a thread already running.. http://www.gt40s.com/forum/gt40-tech-engines-induction-exhaust/36714-header-prices.html

Alan, do the headers in ALL SPF cars all look like Mk2 square style bends from memory...even the Mk1 cars...correct?

 

[Tim Kay]

.....I dunno, why not?....and bolt a 50/5X to iit as well...cost? :stunned: Gee, not a clue but it looks and sounds expensive!!

I don't recall from my own experience; all I can speak for is the FE headers I have now which to my eye look more or less like real Mk II headers (minus the joint in the one vertical section that the real ones have).

Here is a picture of the 302 from Lynn Miner's car P2133 which I assume is using standard SBF headers:



Here are the SPF FE headers on Steve C's P2125

Thats a pretty looking engine bay Tim...

Alan the headers you show are both Mk2 style...the Mk1 is more flowing with sweeping curved pipes and less of a squared off look....as we supply to the 302 based Mk1 cars...

You probably mean like this:



:thumbsup:

 

[Fran Hall RCR]

yes...and like these RCR headers for 302 based engines..

 

[EGLITOM]

Custom RCR 1 3/4" MK1 style header into 3" merge collectors on 408 (351 based)

you can also see the G96/50 6 speed installed (currently have two of them available)

I'll stick with the 347... I just read the header post.

Smart man....

Jim, you might want to consider a 331 instead of a 347. Apparently the lower piston ring on a 347 is just about coming out of the bottom of the piston bore....and the rod angles are starting to get pretty extreme in the 347 too. Just a thought. A well designed and built 331 will crank out 400+ hp/tq, which is loads of power in a car weighing sub-3,000lbs.....
