picked up a 302 short block with some weard casting numbers? they are d4de-6015-BA tag ?019 its a 74 year but d indicates falcon?? reg 6015 part no. but what change is the -BA? im thinken its an ausie falcon block or somthin??? pluss the first number on tag is a 5 or 6 019 ? if enybody could help that would be great so i can rebuild it. it spun a main berring so i picked it up for 100 bucks with 87 e7 heads and roller set up.
Aussie 302's are cleveland based Nothing really oddball about a 74 302 block except with the spun main its gonna have to be line bored
ya its going to the shop as soon as i get the numbers right. the ab change is bugging me i cant find it?
I read it as d -as 70 decade 4- as year, d-as maverick ,and e -as engine. Then 6015 is the engine part ,group number, and the last 2 letters as 1st,and 2nd change on block. The 87 heads are prized for some reason! I could be wrong on some.
cool so it is a mav engine. thanks! im wondering what the first & second changes to the 74 block? besides crappy heads and deck hightthe ones i got are e7's off a 5.0 roller with the roller set up from the same block. i traded mav spindles for em.
Don't worry yourself about the AB suffix, whatever change was made will have no effect on however you decide to use the block. And just the fact that the casting prefix indicates it's engineering costs were assigned to the Maverick (really the intermediate car line here) also has no bearing on anything, your block could just as likely have been installed in a 74 F100 as a Maverick. You've got a 74-77 302 block and that's all that matters. There's nothing special about it, unless it's got the Hi-po main caps, which can be a possibility, but not likely. The deck height is a full .020 higher than an earlier block and easily removed by any competent machineshop if for no other reason than to true up the decks.
sweet thanks . the a b isnt im portant i gess ya im having the deck milled,and bored 30 over pluss im converting the engine to a roller as it has the holes and bumps in the gally for it. i also have a whaind low rize intake with a holly 600 on a 1" spacer. mav oil pan. i need a cam and crank combo and all the usual stuff for it pluss in looken for finned valve covers for it. im wondering what i need for push rods size to put late heads on an eary block?
If it's a 70's block, it does not have the bolt bosses for the roller hardware bolts. One more thing: please learn to use spell checker.
ya it was late last night. shoot i just went out on the porch and threw the roller spyder on the block and your right it dosnt have em. well ill eather get a new block or sell the roller set up.
There is a spell checker? Cometkurt, sounds like you have a tough choice to make. Sale the block, build it to a different build. Or sale the rollers, or use for a future build. I vote sale the rollers
You can still go roller (and I would) just use a set of linkbar hydraulic roller lifters, like Howards offers.
