Okay I need help on this desicion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

CHEVY & GMC FOREVER · 02-24-2005, 07:59 PM

Alright here goes, I am thinking about instead of rebuilding the old 350 sbc...... maybe I'll just buy a 502/502 BBC crate motor instead....... what would you do????

Alexis · 02-24-2005, 08:02 PM

you're joking right

five-O-two

CHEVY & GMC FOREVER · 02-24-2005, 08:03 PM

I am most certainly not

bigcdawg99 · 02-24-2005, 08:04 PM

There's no subsitute for cubic inches. If you have the cash go for the 502!

silvertonguedevil · 02-24-2005, 08:06 PM

Is money an object here?

CHEVY & GMC FOREVER · 02-24-2005, 08:07 PM

Not really, but I'm crazy and I want to go fast....

CPNEJR · 02-24-2005, 08:10 PM

go with the 502 if you have the money and the time to do so

CHEVY & GMC FOREVER · 02-24-2005, 08:11 PM

I don't know though is a 502 good for daily driving???

I'm going with the BB,502/550 will cost about 6500.00$.Plus you get a 1yr.warranty
as long as the engine isn't used for racing.(who's racing,right.there old trucks)But even
if thats too much a create SB is still the better deal than rebuild because I haven't found one machine shop that warrantys. The only time I wouldn't do a create motor is
if you need a numbers matching

**JIMs70GMC** · 02-24-2005, 08:49 PM

502, 502, 502, 502, 502! or a merlin 415 small block?

classicchev · 02-24-2005, 09:07 PM

502. I finally bought one, the Ramjet version though

. It took me a long time to decide. like 8 months, but Im glad I went for it. Price out what a good rebuild is going to be, and in my case there was not much difference in the final costs.
I cant wait to get working on it again, so I can hear that baby purr.

Good luck with the desicion!

Gary Lee · 02-24-2005, 09:14 PM

Gee, when I went from a 327 wild small block to a mild 454 in a 67 camaron, I went from bad to awesome... with half the problems except taking turns fast... but hey its a truck right?

bagged91 · 02-24-2005, 09:51 PM

Definitely the 502. If you can afford the Ramjet, I would go with that. Should help out on economy

(<---an excuse to give the wife) and it looks cool as hell too!

CHEVY & GMC FOREVER · 02-24-2005, 11:06 PM

Well I figure a 502/502 BBC has to be at least 5,000 $ to buy, to rebuild my 350 it would cost (conservativly estimate) 2,000 $ so it would cost less to rebuild the 350, but I would be sacrificing power big time, a 502 would take 92 octane fuel which is expensive, without 92 octane the 502 would not perform as well and would probably have a ping really bad. It's not like I'll be dragracing or anything of that nature, so maybe I'll just soop up he 350 from 255 horsepower to oh say roughly 355 horsepower, that should be good enough for me.

Thank you for all of your imput on my situation.

72 Cheyenne402 · 02-24-2005, 11:16 PM

When I rebuilt my 402 it costed a mint. I could have bought a new 502 but the ### match and that was what I was after. There is no substitute for a Big Block I'm running 3" 3 chamber flowmasters exust with 4" tips. For me there is nothing else. Thats it Raw Power!!!!!!!!!!

jhow66 · 02-24-2005, 11:24 PM

Go with a 502HO--here is what it will look like:

CPNEJR · 02-24-2005, 11:57 PM

The 350 sooped up or not will get better gas mileage but you wont have as much fun

it's really up to you and how much you wanna pay on gas and how much it cost in your area it costs over $2.00 here

mr402 · 02-25-2005, 12:12 AM

It takes a lot of torque to move these trucks. If you don't want to run premium fuel why not go for a smaller big block 454 or 402 etc. I run my 402 on regular gas and get about 12 mpg. Small block can produce lots of HP but low end torque is what you really need. Needless to say my vote is Big Block all the way!!

Rollie396 · 02-25-2005, 02:06 AM

If you don't worry about cash...502.Otherwise,well work down from there.

Drogster · 02-25-2005, 02:51 AM

What are you worried about gas mileage? It's a 30+ year old full-size truck, running a mean, nasty (in a good way), gas-guzzling 350 or 502 cubic inch engine.

It's gonna LOVE gas!!! Either way!

FIVE-OH-TWO baby!!!

**Daubs** · 02-25-2005, 10:16 AM

I'm all for the Big Block. But you might have to upgrade your tranny and drivetrain to handle all that pedal mashing with your right foot!

Big Block POWER! Big Block POWER! Big Block POWER!
