I have used the engines Wrenchbender has recommended a couple times with no problems. The turnkey sounds good too.

John, isn't this the same 307 engine you called me about awhile back? If so, I'll get onboard with the rest of the crew on replacing it with a stock-specification crate 350- - - -just be sure to upsize the radiator to something that can keep the extra ponies cool. I can recall a couple of "upgrades" from small displacement Chevy small blocks to bone-stock 350's that had chronic overheating problems because the radiators didn't get upsized at the same time. Crate engines are OK for people who can't (or won't) do a quality rebuild.

I just saw one of those 195 Hp motors On the internet for just a hair above 2000. I am not sure you could get a quality rebuilt 350 for that money let alone an all new motor with a gm warranty. They are just hard to beat $$ wise.

Can’t remember but either jegs or summit has a crate motor 350 for 1600.

Sorry for the confusion ... it *is* a 307. I had the GMC 305 V-6 in one of my trucks and thought it was pretty much a boat anchor, so I guess I have 305 burnt into my brain housing group ...

Good input above -- thank you all.


We (Chris Sweet, John Vannatta and I) got the old engine pulled yesterday afternoon. For most of you above, it probably would have taken 45 minutes to an hour. It took us three brain surgeons about 4 hours. We ended up pulling the engine and transmission as a unit. This was my very first V-8 to mess with. smile To celebrate, Sweet and I got up at 0500 and went Striper fishing.

This truck is a column-shifted 3-speed manual. The clutch pedal linkage bellcrank rotates on a shaft whose one end is on a plate bolted to the engine block ... ? ... If I specify a 350 for a 1969 application, will it have the holes for this plate?

Thanks,
John

I believe the 350 block will have the bolt holes for the clutch linkage. If not, it's a fairly simple project to fabricate a bracket from angle iron that attaches with the bellhousing bolts to support the inboard end of the clutch pivot shaft. We used to use slightly modified pickup clutch linkage on the round track cars from the late 1970's which were not sold with manual transmissions originally. On the 1/4 mile tracks we used Muncie 4 speeds in 2nd. gear and 4.10 or 4.56 rear ends to get the right RPM range down those short straightaways. Off the turn at 3K-3500 RPM, and hit 7K 100 yards later before chopping the throttle for the next turn!

The late edition crate engines are a hybrid of sorts to fit numerous applications, they have the front engine mount locations drilled and tapped for the early engines and the center mount locations as well. As far as I know all other mount locator holes in the block and heads are in place. They also have dip stick holes cast in both sides with a plug for the unused hole.

Think about the discussions (no, I won't call them "arguments") stovebolters who encounter one of those hybrid blocks 50 years from now will have! If human nature hasn't changed much by then, there will be a few self-appointed gurus who will spout all sorts of off the wall pontifications about those engines!
LOL!
