Oh what to do!
Have 70 Torino 302 in 65F100 and had to tow it home yesterday. Sound of gears and metal grinding in the engine. Engine is not seized, but did sound major. Had to continue to drive in this condition for 100yrs to avoid hazard condition. Engine rebuilt few years ago. Has Edelbrook intake w/ 4bl., Edelbrook valve covers. Also, installed headers, and elect. ign.
Have access to 351 W. long block that will need to be gone thru. IF recall does not have intake manifold, harmonic balance, generator, pulleys, or brackets. Does anyone know if any of the missing 351 items, and 302 parts and/or upgrades interchangeable? Issue whether to purchase replacement 302 and rebuild vs rebuild 351 and purchase items (upgrades). Hopefully, 302 will not need major surgery, but need transportation so leaving in couple days to pick up other vehicle and whether to bring back 351. Any suggetions, input appreciated.

Sorry about your loss...and to have to inform you that only some of the parts you have now will fit the 351. Valve covers, no problem. But the intake manifolds and distributors are different between the two engines so they won't interchange. The headers may possibly fit, at least they will bolt up to the heads okay but the 351 is both wider and taller so there might be some chassis fitment problems. The imbalance is the same between the two engines (Pre-'81 302 and all 351W are 28oz.) so I think you could use the balancer from the 302 on the 351, but you may have some problems with the brackets. I'm kinda thinking you need a more complete 351, or stay with the 302.

Appreciate the input. Did not consider the chassis fitment, thought it would be a direct swap. I do not want to get into that issue, at this time, not to mention addional cost of replacing upgrades and missing items. Seems less cost and labor if stay with a 302.
thanx again,

Well, the engine itself is indeed a direct fit and in a truck (especially one that originally had an FE under the hood) should not be a problem, but what I was saying is that the headers may cause a bit of a fitment problem when bolted up to the 351W. If you have a crossover tube on the pipes you could have a little trouble when trying to spread them further apart to fit the 351 among other problems. Me, I'd probably stay with the 302 anyway, I'm just more of a 302 guy. And when you already have all 302 parts, it just makes more sense for simplicity's sake.

Not sure what effect blown head gasket would have on the engine. Could it appear engine had sucked a valve, timing chain, or gear were binding? As noted, engine came to a stop and it sounded as if there were gears binding and or time chain slipping. Not that knowledgeable and probably should have investigated further before tearing engine down. Pulled timing chain cover, heads, and found no evidence of a problem. No metal found in pan, but was full of antifreeze. Number 1 cylinder appeared slightly scared but nothing on cylinder head to suggest cause of problem, could be a pre condition. Only items left is the oil pump, and the cam, not sure if removing cam is beyond my level of experience, with lifters and push rods removed, it appears few bolts the cam will slide out. Don't like assembling without finding cause. Hate thought of removing engine, or taking to shop for rebuild. Any suggestions on brand of gaskets, purchased Earl's gaskets for headers and valve covers and pleased with quality. Looking for quality head gaskets.

The cam will be easy to take out. You already did the hard part. If the motor is still in the truck make sure you have enough room to pull it all the way out. Take those bolts off and the plate that it holds. I usually put the cam gear back on to give me something to pull on. Sometimes you need to pry a little on the gear to get it started. Then slowly slide it out so you don't nick the cam gears.

Appreciate the info. Cam looks okay. Now that engine is disassembled not sure how to get the valve adjustments. Understand they are pre-loaded, does this mean only need to torque to specified value to adjust? The manual I have does not list a value, nor does it give any indication who to go about it. If can get running, intend will take to reliable shop to make final adjustment. Still not sure what problem is, will contact shop where engine was rebuilt and inquire if blown head gasket would have cause the symptoms described. Thanks again for the info.
