early bronco

[Anonymous]

i am considering using a 250 in an early bronco.

can i use a 144 head on it?
get bigger valves
forged pistons
six large motorcycle carbs
cold air intake split up six ways by large pvc pipe

this is an early bronco with four speed wide ratio 4.11 rear

im sure this is possible to certain limits, read the sticky thread about 144-250 head swap faq's.

Multi-carbs and a turbo are not really compatible technologies. You want one or the other. The turbo needs one big carb sized for the type of application (blow-thru or draw-thru) You really need to read MacInnes' book Turbochargers if you're planning on a turbo with carb.

Turbos don't work well with big cams either. Too much overlap and you just dump all the boost right out the exhaust, which both robs power and raises exhaust temps.
