Customer q:

Hi, I'm building a 545 ford motor on an eliminator block with P51 heads. My question is about the fit of the Speedmaster 8 throttle body manifold system. I understand some minor modifications may need to be done, but is it suited to this combination & do the intake ports match the p51?


ac = No

drivewheel = 2WD

engine = 545ci

fuel = Efi

make = Ford

model = Engine build

pwrbrk = No

pwrstr = Yes

trans = C6

year = 1968


Hello! Thank you for giving Jegs the opportunity to assist you.

The Speedmaster EFI throttle body is designed to fit standard Ford 429/460 heads, It also appears the P51 head uses this same port configuration. 

Consider checking out our high-temp gasket silicone or intake manifold gaskets as you complete your project.

Should you need further assistance please feel free to contact us.
