pinto build


esky 73

Recommended Posts

yeah i am going to build it to cope with a hiding, i bought the escort as a trackday car so it has to be reliable, head work forged pistons, steel rods and i am going to use a old dry sump set up off one of my old formular ford motors, i would like it to be as quick as it is with the ca18det but this may not be realistic, i'm not going to build it half assed, do it once and do it right ( hopefully!)

What sort of build? judegeing my the books a a revving, big head build? got any particular aims for it?

Well you have the bottom end sorted!

Rods and pistons are the weak points.

Get the biggest inlet valves you can. If you are going for a big lift cam reinforce the cam towers and meke sure you check the valve springs for coil bind and that the spring retainer isn't hitting the stem seal.

Are you tuboing the 2L?

Here's the flow data of the std CA vs the std Pinto and the CA kicks the Pinto's arse, which is not surprising considering that the CA is a modern 4 Valve head. Se how the CA exhaust out flows the 2L inlet up to .200 lift

Just incase you didnt know (which you would if youv read ya books) the porting of the head is important with a pinto.. Follow Vizards book re head

Guy from Puma racing also has some good publications on race pintos.. Think his name is David Baker.. or maybe Peter

edited cause KY said so. :mrgreen:
