How do I I.D. a 340 engine? Looking at buying a 340-4 and I am trying to find out what it came out of. Are there any number lists anywhere on the net? Have been looking but can't seem to find.... o No:
Try looking around on www.buicks.net I'll try to find the page with 340 id info and post it here too. Try here: http://www.buicks.net/years/67/67tech.html#engine ident This is even better: http://www.buicks.net/shop/engine_ident.html
Oh yeah...WELCOME to the V8 board! We would love it if you could sign at least your first name on your posts...we're a friendly bunch around here, and it really adds to the personality of our conversations to be able to address each other by name! :TU: :beer
Thanks for the quick reply David.... I just know from looking thru all the posts since becoming a member that this is the right plce for me and my Buick :grin: :grin: Drew C. 1964 Skylark conv.
If I were you, I wouldn't buy a 340-4. And, I've owned one for 36 years! Mine does run very well and has great power...but, Seriously, these were two-year-only engines with almost no after-market parts. And, the 10.25:1 means you have to mix racing fuel to manage the pinging. You'll never stop it, just keep it at a reasonable volume.... If mine ever blows, I'll bite the bullet and replace with a new crate Chevy 350. No flames, please, I know all the arguments....
Thats a blow to the chest. anyway i do like chevies, just not in my lark. just wondering what type of block comes w/ a crate. LT1?? or something else????
Crate engines How about I build you a nice 350 or a 455 Buick engine and crate it up for your car???? AND I can guaruntee it will have more power and torque than a 350 crate motor!:Smarty:
I knew that remark would draw some reaction. When I sat "crate" I mean the long block 350's you see widely advertised in the old car mags. Some are just new GM block assemblies in crates. other are built to various power levels by firms like Edelbrock. Mike - Thanks. Something to think about over the winter.
I'm just wondering when you say mix racing fuel....what octane level do you have to mix too? Our local pump has 94 octane, would this not be a high enough octane content to cure the pinging Drew C. 64 Lark conv.
If you calculate the octane from the numbers given in the 1966 Buick Chassis Service Manual, you come up with a modern octane rating of almost 97. I mix VSP 110 red into the tank at a rate of 1 to every 4 gallons of 93 gas. Been fighting this pinging probelm for over 20 years.....
Drew, the 340 and 350 Buick engines mount the same. Almost no reason NOT to go with the 350 vs a 340. Much better aftermarket support plus more power to start with. IMHO Dan
To tell the truth that is what is in my car now....however I want my car to be different. I have had soooo many engine ideas go thru my head that I am now totally lost as to which one to put in, 340, 350, nailhead, even thought about chevy :eek2:. The reason why I inquired about the 340 is because I found a running one from a 1967 GS, so figured already is a hi-po engine just bolt in and go!! Winter is on its way here in the north so will be putting the car away and working on it and I am looking forward to pulling it out next year with something unique under the hood. Around here just having a BUICK is different, a BUICK powered Buick will be extremely off the wall:laugh:
