DART does NOT make a head for the SBF . I think you are refering to World Products Windsor Jrs., which is in no way affiliated with DART. They used to share a building about 6 years ago, but that was about it. Maybe you should re-phrase your question, and you might get more responses, because people might not know which heads you are talking about.
I have World Products Windsor Jrs. on my set-up. My 1/4 mile times are in my sig. I know it's not very fast, but, keep in mind that this was on regular street tires and my car has very stiff 'road race type' suspension on it.
My friend had an 85 GT with Windsor Jrs, B cam, 1.6s, Performer RPM and 650 dp. He had a roadrace type suspension too, C springs and the car ran 13.2 in the 1/4 with ET streets don't remember the MPH. That was with 3.73s and a 5 speed car. The heads were unported and that car ran strong.
combo is in sig. that is at full weight of 3400. car is stripped down now with a cage in it, will see how much it picks up from a diet... hopefully around mid 12's on a mild combo.. those heads are good for budget, if i had the money i would buy AFR'S. but i didn't so i went with these and i am happy for the time being
I have 342 ci stroker with windsor jrs. heads, victor 5.0 intake, tfs stage 2 cam, longtube headers, 24# injectors, 75mm pro-m maf, soon to be 36# inj. and 80mm pro-m maf. my heads been fully ported and polish. best time to date [email protected] 112 with 1.53 60' and that was with a ported gt-40 intake running out fuel on the top end. these heads really come alive with a lot of head work.
See sig. Cleaned up heads, dual springs, seals. 1.6 Scorpions, 1 piece Comp PR's, FMS lifters, chain, balancer. Cleaned up lower.
Add the other typical mods. 75mm MAF, 65 TB, 24's, 190 FP, AFPR.
FMS shorties, X w/ cats and Borlas.
Mean-ass idle at 800. No shakin', spitin' or missin'. Runs like a raped-ape. No dyno numbers yet. Did I mention I love the cam?
