302 sbc?
 
jus got a new car its a 29 model a and i was told it had a 302 form a 69 z28 does anyone no the casting numbers or how to identify it?

justin45 08-04-2010 12:16 PM

and has anyone had much experience messing with them

fla1976 08-04-2010 01:19 PM

There should be a "DZ" on the engine ID pad.

justin45 08-04-2010 02:06 PM

are they easy to make good power?

kwkracing 08-04-2010 02:53 PM

3" stroke 4" bore

Scooterz 08-04-2010 03:07 PM

My buddy has a DZ in a stock Z28 69 camaro. It is all top end, good rpm's, torque is not is finest attribute for sure... has to spin the tires to get a decent launch, but it is all stock w/ the solid cam & 373's. Neat motor, but needs low-end assistance (his car is 4spd). It is a dog until about 4500RPM then it gets it.

justin45 08-04-2010 03:24 PM

its in around a 2000 lb car with me in it but i was told it had a eagle forged crank and a .5 something lift flat tappet but it does have roller rockers and a rpm air gap

TheRabbit 08-04-2010 04:05 PM

Whatever you do don't swap it for a 302sbf!!
That would ruin the property value of your house and you neighbors too!!!!
Heard of 'em but never messed with one.

justin45 08-04-2010 04:21 PM

never would i swith out anything for a ford motor its always a chevy

kwkracing 08-04-2010 04:46 PM

the short stroke works well at high rpms. You must have a good set of heads, cam and carb to make something light go fast with a 302. Your .500 cam is way to small. Drag racing these 302's you want to turn them atleast 7500

justin45 08-04-2010 04:50 PM

it realy aint gona be raced jus somthin to cruise but i there stock heads and i hadnt realy looked to much at the carb yet but it does shit and get it thru first gear

Tod74 08-04-2010 10:00 PM

iF IT IS A REAL 302 WITH THE LARGE JOURNAL CRANK THE CASTING NUMBER ON THE CRANK WILL BE 1178. Someone could put the 302 rotating assembly in a 350 block and still have a 302. 1178 crankshafts were the only ones used for a large journal 302.

You are so right!!!!!!!I bought a backhalf vega off here last year that supposedly had a all forged 355 4 bolt with dart 230 heads,big roller,victor intake etc.After tearing it down it did very much so have dart 230 aluminum heads(I could see that on the motor) comp roller 630 630..BUT!!! it had a cast large journal 327 crank ,stock rods and trw 12.5 to 1 pistons.EVERY rod bearing was wiped.It did however have a 350 4 bolt block(that I re-used)..Unless you take it apart to see...you never know what your buying.... :roll:

justin45 08-05-2010 03:21 PM

like I said just because the block is a 350 block it doesn't mean it is a 350. If it has an 1178 crank in it it is a 302.

This is what I was thinking too. I thought I read that somewhere too. 327 block, 283 crank??

fla1976 08-06-2010 01:05 PM

The 302, 327 and 350 all have a 4 inch bore. The only difference is that some of the older engines utilize a small journal crankshaft. The 302 has a 3 inch stroke, the 327 has a 3.25 inch stroke and the 350 has a 3.48 inch stroke.

Tod74 08-06-2010 03:57 PM

The 302 was a 327 with a 283 crank as was said...4" bore 3" stroke..BUT IN 1969 ONLY they used a LARGE JOURNAL crank. 1178

67 and 68 were small journal

lively 08-06-2010 05:21 PM

302 IS A FORD :lol: :lol: :lol: :lol:

burnskustomz 08-07-2010 12:34 AM

No 302 is Chevy territory boy!! :lol: :lol: Chevy screwed Ford by copying the Mustang but we can't help it that Chevy perfected what Ford couldn't lively :lol: :lol: :lol:

Tod74 08-07-2010 11:25 AM

If you do havbe an 1178 crank it is wortyh some money. I had a NOS one that my dad gave me...he had it ratt holed all these years with plans of building a 302. I sold it for around $1000 on ebay
