Hey guys,

Ive been looking for a motor and came across this..

http://seattle.craigslist.org/kit/pts/1889296852.html

what do you guys think? Im not an experienced engine guy by any means thats why im asking.

Let me know

Matt

If you leave it as is yes it looks like a good deal, but don't buy it thinking you can build it to the nines

muthstryker · 08-09-2010, 04:50 PM

Ya I would leave it as is, the guy said its around 350-375 HP. Figure thats good enough for the truck, big improvement over the 305 thats in their now.

84bigblockswb · 08-09-2010, 04:54 PM

In my opinion, looks like a pretty decent deal. The 781 heads are the open chamber/ oval port and flow pretty well. Maybe you could see if guy has any reciepts and give the shop that did the engine work a call. Good luck.

84bigblockswb · 08-09-2010, 05:01 PM

And by the way...... I would go with the roller rockers cause you cant buy a set for a big block for 100 bucks!!

Bigg G · 08-09-2010, 04:58 PM

All looks good except the pistons look to be used......ary they ?????

71swb4x4 · 08-09-2010, 05:03 PM

It looks like it's probably an alright deal.

They are used. In his ad he says the motor has 5,000 miles on a rebuild. They pulled the heads to check it out.

muthstryker · 08-09-2010, 05:17 PM

I would be going with the roller rockers, cant beat 100$. Any questions I should ask the guy? Like I said new to all this...

muthstryker · 08-09-2010, 05:19 PM

there is also this one...

http://seattle.craigslist.org/sno/pts/1885393195.html

The guy is about 20 mins from me, the other guy with the first motor I posted is about an hour and a half..

camshaftgsxr · 08-09-2010, 05:31 PM

Can't say much about the second but dayum... I wish big blocks were plentiful where I live.. You are soo lucky

muthstryker · 08-09-2010, 05:39 PM

So No on the second one?

camshaftgsxr · 08-09-2010, 05:52 PM

Not at all I'm just not a block number expert I don't know much about the second one so I guess I'm out. And you'll have to wait on someone else to stumble in here sorry bout the confusion

camshaftgsxr · 08-09-2010, 05:54 PM

I just reread the second listing I would by that one, ask the guy what he had done to the heads the post kinda mentions they might have had som work done but anything you can hear turn and run is a sure bet not a crap shoot

mrbox43 · 08-09-2010, 06:24 PM

the first motor looks real nice good price too and i like the fact that you can go see the second one run and the pics looks like he has a set of gauges on the motor, as for the casting number try google and see what comes up. id say go look at both if there close i just let one go a few months back it was a gm goodwrench 454 from an old 80 somthing box truck for $900 and that thing was in worse shape then either of those

muthstryker · 08-09-2010, 06:34 PM

Called and left the second guy a message, if he calls back im going to look at that one first.

muthstryker · 08-09-2010, 06:43 PM

Just got off the phone with the second guy, the heads on the second one are 049, he said they were similar to the 781s? Also he said it would be a good pulling motor thats about it. It was pulled out of an RV when he got it and then he rebuilt it and its been on the running stand ever since.

camshaftgsxr · 08-09-2010, 06:48 PM

Here's the 049s http://67-72chevytrucks.com/vboard/s...ad.php?t=40273

If it was out of a running vehicle I'd say maybe, depending on comp ratio you may have a stud or a dud

muthstryker · 08-09-2010, 06:51 PM

Ugh this **** is confusing...

camshaftgsxr · 08-09-2010, 07:12 PM

Basically the heads it has flow the same intake I very small amount better exhaust but have larger chambers than the heads on the first motor I don't think there would be a compression problem so go for it if you feel it runs good on the stand

camshaftgsxr · 08-09-2010, 07:15 PM

Larger chambers mean lower compression not a big difference but by good pulling motor I think he meant it's not super powerful but high compression pistons and a good head port could def fix that is the bottom end cast or forged?

camshaftgsxr · 08-09-2010, 07:21 PM

The second motor is the one I would buy and trust me if I was close enough I would buy it if you didn't

camshaftgsxr · 08-09-2010, 07:23 PM

I can't find a busted a$$ shor block for a grand

muthstryker · 08-09-2010, 07:33 PM

Any particular reason you would choose the second over the first? Besides the fact that you can hear and see it run?

muthstryker · 08-09-2010, 07:29 PM

Haha, I will go check it out. I basically want a motor with some kick, I want to beable to take off on the highway if needed or take off quick from a stop..

I want to be thrown into the seat. LoL

muthstryker · 08-09-2010, 08:04 PM

Could I swap out the RV cams in either of these motors for something a little better to get more power out of them and get a better rumble or?
