i have a 90 sc that has the efi 3.8sc motor in it. i also have an 85 mustang convertible that has a 3.8. does anyone know if the efi block will accept the carbuated intake and related componets? any and all info will be greatly appreciated. thank you.
my first thought would be you should also carry over your heads as well. Compare the two sets of headgaskets at your local auto place and do a stare and compare. they both should be darn near the same if not a match.
while your on that, price the 4.2 L rods, pistons and crank.
