anyone out there ever ran an iron duke? i have a pontiac crossflow head and all the rest of the parts"h-beams, pistons rod etc.." was going to build it for our race car but dont want to change classes... the motor should make around 375- 400 hp but it wont make more than 200 until its over 4000 rpm.. the cam i have has around .800 lift and lots of duration..

if i do it i'll propane it and maybe turbo one day.. just wondering how light it will make my front end and if anyone thinks it will be worth the while... the motor is worth well over 8 grand and i have everything to build it. its either put it together for free or make my 1600 a 2176 and see how it goes..

i found a side shift 6 rib i was going to get.. someone says i can change the nose cone and convert it to a front shift.. is this true? and will this tranny hold 400 horses?

Is it from a a/c or w/c w/c 094 are stronger but can not be made nose shift . The shifter is in the side of the main housing

Ok the only iron duke i know of is the Gm 3.0l that they use in boats and forklifts is this the same engine??

somewhat... the iron duke is a 2.5 liter.. either a 151 or 153ci.. i know they come in boats.. the head on my pops jeep is off a boat. they flow way better factory than a land motor so better start for hours of p&p..

this is a few clips of the jeep at gravelrama.. he built it in 96 and has put rods and rings in it once in 2000 so its pretty reliable for a factory crank with aluminum rods.. i will run steel h beams.. the only major problem is that the big block triple valve springs have pushed through the head in the intake runner do to so much port work on a non crossflow head!! he has had to weld under the spring plate twice and is leaking again now.

i sell them for 300 and i have them all the time if i cant pick them up for 250 i dont buy them like i said i dont like payin over 4 for a side shift...buy the time you buy the intermediate house and nose cone and switch it over you have way more in it then its worth...the side sift you want is out of the watercooled and they can be had for around 4 or less the last one i had i picked up for 300.00 and im suppose to be gettin more just havent heard from my source lately....just my cple cents

well guess i'll wait it out.. i was going to get a 3 rib for 400 a few weeks ago.. glad i asked a few questions before wasting money

what bout the a/c 6 ribs out of like a 76 what they worth
