Found a block, yes or no?

[ivan12]

I just bought a used D1SC procharger and was going to slap it on my car after I swapped in the 92 stock block I have at home since mine is on life support. Then I came across some edelbrock performer heads on the classifieds and bought them to run with my eddy intake. Now I've run across a 331 stroker, it's going to need a good cleaning but I have a machine shop that can go through it. I spoke to the guy and he wants no less than $400, what do you guys think combo wise and the condition of the block? I know it's hard to judge a block from pictures but I'm just trying to get some input before I buy this thing. I know its not in the best shape, but I need to get my car done in the next couple of months and an aftermarket block is out of the question at least for the near future.

I would go aftermarket 302 block, your going to do it anyways. A 331 w/ eddy top end and a D1SC should make damn good power, most likely more than a stock block can handle for very long. So why not budget in a Boss block or something like that, and then build a better motor.

 

[ivan12]

I don't go aftermarket because I'm supposed to be saving for the big wedding not spending more cash on the stang LOL. After June the projects are going to stay in the back burner, and there's no way I'm going to be able to afford a boss or dart block before then

Then I say hold onto the D1SC for now, just run the eddy top end on the 331 and call it done. Have your shop go over the block and run N/A for now til you can get an aftermarket block.

Never thought about that, I guess the S/C could wait a while

If you boost a stroked block, that's more likely to break. So stay N/A for now, wait til after the wedding and then find a good aftermarket block and then swap all of your stuff over in a weekend or 2

Then whats the fun in it

Just boost it, and try to stay outta the throttle, until after your wedding....

 

[ivan12]

I trust myself not to beat the crap out of it, it's now my other weekend car and I've only been to the track once and I didn't like it because it's only 1/8th mile and the other nearest track is pretty far away. I guess my concern and questions were more towards does the block sound like a good deal? Or is my top-end to small for the block and boost, I guess the latter has already been answered. I'm picking up the block tonight and we'll see how it goes

I say go ahead and boost it on the stock block and just baby it around if you're truly worried about breaking it. Mean while, find yourself a A4 block, or R302 block. If you don't have that kind of cash, I think the B50 SVO blocks are supposed to be a LITTLE stronger than production 302

Ya i wouldn't trust that 331 for 400 bucks. That thing is probably beat to hell and you might end up having to buy a new rotating assembly anyway. If you wanted to you could always do a rebuild of your block with some .30 pistons for 306 c.i. and then put your eddy's on there and if your still not satisfied slap the D1. Is a after market block necessary with that setup? No, gives you room to turn up the boost. But with a proper tune and a fresh block you should have 400+ hp which would be plenty until later on down the road you can go nuts with a after market block and lots O boost.

+1, its the stuff you cant see that hurts a shortblock, like micro-fractures and crystalizing of the metal in critical areas.

sell the d1 and put that towards a nice block.i know that a good blower at a cheap price is hard to find...but the best foundation far outweighs the blower find.jm2c

 

[ivan12]

The thing is I'm never able able to put a lot of money together at on time, I've had the mustang for 6 years now and it wasn't until a few months ago that I was able to put the money together and pull the trigger. Right now I'm leaning towards rebuilding the block and running it without the S/C, I'm pretty sure if the stroker can work out plus the eddy top end I'll be satisfied for a while, if that doesn't do it though I'm definitely slapping on the D1 and babying it until I can afford an aftermarket block

 

[mikey94gt]

I say F it and build it anyways..... is it your DD? if not, then if it blows..... more like "when", then either just slap another junkyard sourced shortblock in and drive it, or save your $$ for the aftermarket block while beating on what you already own.

IMHO, I would just use a 302 bottom end, screw the stroker for now, use the $$ to tune it when your done....

Why even bother with a 331?

A rebuild of a stock block with stock internals, the eddy setup and a D1 will make more than enough power to split the block in two.

Rebuild it, throw the blower on and have fun.

400 for the 331 or 400 for the machine shop to look at it?

bearings, upgraded hardware (arp) and if the bore can't take stock or slightly over stock rings then get a set of stock replacement pistons and keep the compression around 9-9.2:1. run the h/c/i, blower and enjoy the car


going to give you honest advice. my mid 90s setup of stock shortblock h/c/i and the blower was the most fun. car made good power, could drive it to the moon, and was dead reliable. i wish i never changed from that setup.

It was $400 for the block, machine shop is going to look through it next week

400 for a bare block is too much. the blocks new when they were still available were less then 300. i just got a mint stock bore 289 block about a year ago for 150 so i didn't have to use the 66s stock block
