Hey guys, i just got a 350 with 14010207 on the block. Anyone know what this is, and would you recommend building it for a street car? Im looking at the 450- 500 H.P. range. I was told it came It out of a Truck.

does it have 4 bolt mains?
I would look at a 383 stroker kit with a nice set of hi-flow heads and beefy cam and you should be in the 450-500BHP mark pretty easy.

14010207 is from 80-85 Passenger car, Malibu and Camaro and 80-81 trucks light duty.

It's a 350 block and I would highly recommend it for a street Rod

The 383 is a good engine and I would recommend that the block be a 4 bolt main just for insurance.
Everything else depends on the size of the purse.

There's a pad that sits forward of the right cylinder head that has some numbers and letters stamped into it....post the numbers and the letters and it can be decoded as what it's most likely out of.

Although you could use this block as a foundation, keep in mind in the late 70's they decreased the nickle content in GM blocks. The nickel is what makes them strong. Me personally I'd look for a block that was cast before 1975. The old 3970010 casting blocks are preferred.

Also to build it for the 450-500 hp range you may want to consider installing a stroker crank and using a set of AFR heads. Also consider a hydraulic roller cam....that oughta make it produce some numbers and still be streetable.

Wonder if this guy knows how much money it will cost to build a 450 to 500 hp. engine? I also wonder what he intends to use it for, getting into that range doesn't usually make for an easily streetable powerplant.

Do you plan on drag racing it, just cruising, hitting with any nitrious etc?
Just from my experience in motor projects , do you research and when you figure out a budget... double it. There will always be things you've overlooked and didn't expense in.

Now I'm not a SBC guy so what I've got to offer is from what a friend built up. Long story short this guy had a couple of 350's that were in a 26' Wellcraft Nova (boat) and they needed freshening. He basically got talked into building them up instead of just a standard rebuild. These are 2 bolt main blocks, cast cranks, and stock rods with ARP bolts. He added Canfield heads, some forged pistons, and a pretty sizable solid roller cam. When he got those together and back in the boat it ended up running 73mph on GPS, which for an old Nova is pretty scary. He ended up falling into a deal on a 31' Scarab with no power. He thru those small blocks in that boat (boy did we tease him) and believe it or not that boat runs high 68 on gps which from our estimates puts those motors around the 415hp range. He spins them 5900 and has about 5 seasons on them. Its pretty unbelievable they are still together... I'm sure when they do come apart it will be bad though.

If this is going into one of the General's "built for comfort, not for speed" chassis, that's going to need some upgrading as well. Brakes, if not a big brake kit at the very least upgraded front pads. If you really make 500 HP, you will need some more serious shocks, maybe springs too. Maybe some sway bars.

Wheels and tires, particularly tires, you need to budget for some serious skins...

Transola. Don't put a tired, worn trans behind this motor. Me, I'd try to spring for a Richmond Gear or similar 5-speed or even 6-speed, maybe you can find a Tremec in a boneyard.

Might be best to shoot for more like 375 HP, that's very do-able, without going to RPMs that the stock rods are not really good for. And can be done with a cam that will work with a top gear that will have you a little below 3000 RPM at an honest 80 MPH cruise, and a compression ratio that will let you use pump premium unleaded.

You didn't mention ignition, offhand how about an HEI?

I've decoded allisonguru's block as from a 1981 C20-C3500 truck...it was rated at 165 hp factory, 4 bbl carb, and I believe also a 4 speed trans. So it's definitely a truck block.
