My local shop can build a 383 for about 1300 I just need the block and
heads. -----Original
Message----- John - I can't really comment on
whether these are good deals or not. What I can say is that
for the money they're talking about for their "hi-performance" motor,
you could get more HP from a GM Performance crate motor from Summit. Really, it depends on
what you're looking for, I guess. For that money, if I had a 350 already, I'd
take it to a good local machine shop and have them do all the machine work, buy
my parts and put it all together. If you're uncomfortable
putting it together yourself, you can have the machine shop put together the
bottom end, dial in the cam and then you can do the rest really easily. As for 2-bolt vs.
4-bolt, it shouldn't matter to you. I've heard of people putting out
500hp+ on 2-bolt mains. If you're not going balls-out racing with a
really high RPM engine, a 4-bolt isn't necessary. Karl

[mailto:[EMAIL PROTECTED] I
am talking with a company that has 4 possibilities for me for a 350 crate
engine. They have 2-bolt and 4-bolt mains, and each one is available as a stock
rebuild (+.030, 8:1 Federal Mogul composite pistons, stock cam) for $1049 or a
"hi-performance" rebuild (+.060, flat-top pistons, hi-per cam) for
$1589 (both prices after core return and free shipping either way). They say
the hp model can be set up to put out about 300HP w/ a good intake, 600cfm
carb, HEI, and headers, and is set up for more torque in the low band but
pretty much the same performance as the stock engine at highway speeds. He says
that this one is really for people who are either going to be towing something,
or just like that extra torque when pulling away from a dead stop. He said that
the stock rebuild model would typically put out about 250HP w/ stock-x-mans and
stock cast iron intake. Apparently the
drill is to see if your current engine is 2-bolt or 4-bolt and they replace it
with the same thing. If you want to "upgrade" from 2-bolt to 4-bolt
you forego the core return of a few hundred bucks, but either way you can
choose whether you want the stock rebuild or the hi-per rebuild. He also said
that even at 300HP a 4-bolt main is not really necessary, and told me an
interesting story about how the 350 came about to have a 4-bolt main. He says
that for a long time, wreckers (tow trucks) only came with the biggest big
block engine that was being offered. Apparently at some point in order to make
cheaper wreckers, GM came out with 4-bolt 350s, and the reason for the 4-bolt
main was simply because the driveshaft would wobble when the PTO kicked in as
you were lifting up a 5000 pound Cadillac. So, he says that the 4-bolt main was
not so much to contain the forces that the engine puts out when driving, but
was really a tow truck thing to compensate for the load that the PTO put on the
driveshaft. He also said
they could sell me a 2004R w/ new (not rebuilt) torque converter for $1049 w/
free shipping. bowtietransmissions.com has them for $895 but that appears to be
w/o the converter and plus shipping, so I figure I may as well get both from
the same place and only have to wait for one delivery. I will probably go w/
the hi-per model because I do want that take-off speed. That's half the fun. John Nasta |
