Around 3 months ago I 350 swapped my Monte Carlo
It’s a 70s 010 4 bolt 350
I found this one on offerup
Guy was real cool i ended up picking it up for $400 said he didn’t know anything about it, he did a ls swap for a customer and the customer left the engine with him just knew that he was having problems with the starter and “didn’t like having to adjust the carb all the time”
It came with a lot of extra goodies too, front accessories, victor jr. intake, edelbrock 1406 carb, hedman headers, beautiful tall Chevrolet valve covers, and original GM oil cooler adapter
So I brought it home and started to pull all the accessories, the pan, timing cover, and valve covers to redo the gaskets
So far things were looking really good the rockers and springs look fairly new
It came with that gear drive timing set, it’s cool and all but I prefer my double roller so I pulled it off my 305 and threw it on the 350, the double roller is fairly new just a couple months old at that point
I also put in an ARP oil pump rod for good measure just forgot to take a picture of it
My phone froze and deleted a lot of what I wrote after this
kinda pissed not gonna lie
We pulled the 305 and dropped in the 350
Yes me and my buddy wear slides working on our cars we like to be comfortable
we know it’s not the safest
Swapped my performer intake on in place of the vic jr (I plan on a air gap intake)
Also dropped that horrible chrome thermostat housing for the one on the 350
Thank god my buddy had a ps pump on warranty at the zone so we threw that on but what I didn’t know there’s too different styles of pump one sits straight up at 12 o’clock and one sits slightly to the left or something like that but there’s too different brackets and the 350 bracket was too tight looked like they over tightened it so we had to modify the 305 bracket, nothing a grinder can’t fix
After letting the end seals dry and double checking everything we turned her over and she grinds like crazy starts up and runs but that starter is not happy, kept trying to get it to stop grinding but no luck after a few hours got it the best I could and rode it out for like a week till that flywheel and starter were done for. At the time I didn’t know about starter shimming I never had to do it with my stock starter and 305 when I took it off and another big problem I have a defective block, long story short in the 70s one of the gang drills for starter bolt holes was unaligned so the holes were drilled to far from the crank 1/4 to 1/3 of sbc are affected by this. GM came up with a bandaid solution and it was a new starter that had the gear further out from the case and closer to the flywheel but it was only available for fleet vehicles (police,taxi,etc)
I didn’t know about this till I did my research obviously so I got my self another starter and luckily the same buddy had a starter warranty and thank god it was the offset bolt holes one that’s the one I needed
got another fly wheel and got to shimming
Also had to modify my old 305 starter bracket to fit on the 350 since it didn’t come with one, there’s two different types the long bracket and short thankfully I had the long and I needed the short. Would have been better if I needed the long bracket on the 350 but like I said earlier nothing a grinder can’t fix
I used so many folded in half shims on the outside starter bolt to bring the starter closer to the crank but it’s all good now, I perfectly fit the Allen key in between the shaft and the flywheel and everything worked out great. Probably missing a couple little things but that’s most of it.
7 days start to finish
Daily driver, no problems, I feel like I didn’t too bad for my first swap
