GranSportSedan - makes sense to me about starting off with the 340. How hard is it to come across a decent 340? I'd think they are about the same difficulty to find as a 300 from what I've seen. I had my gall bladder removed today so I've been medicated and sleeping he bigger part of the day. Surgan said all went well so in a ccouple of days I'll be back to normal (if my wife says so!!). Thanks again for all the info!! Doug
Doug how far are you willing to drive. Im up here near sacramento. If i can remember correctly there are a couple up her in a place called the buick bonery. ive also seen them pop up on craigslist. thats how i found mine. the best other option is to buy a junk car that had one in it and then take what you need and sell the rest.
Doug http://goldcountry.craigslist.org/cto/1914288542.html Heres on option hes selling the car which has a 454 chevy in it but he says he has the original 340 for it. might try to just buy the 340 from him worth a shot.
Dan - just started exploring the option of going to the 340, I'll have to admit about the only thing i know about them is that alot of stuff from the 300 and 340 are interchangable and thats about it. Concerning driving, i guess that depends on how good a deal is and the fact of deminishing return (if it costs more in gas and time is it worth it!!), know what I mean. Anyway, I guess currently I'm in the data collection mode and trying to learn all I can about the 340 (I'll have to wait till the oxycodone wears off!!:TU: ). Any info you want to share about the 340 I'd love to hear, I'm just tryimg to fill up my thimble sized brain!!:Smarty: Thanks, Doug
one thing to think about is ive been contemplating is i know the 64 skylark with the aluminium heads had 11 to 1 compression im not sure if it was different pistons and diferent cc combustion chambers on the heads but it might be someting to think about for getting more power. i think me and ponch are at teh same point in our builds of the 340 im just trying to save up enough to send mine out to eh machine shop to make sure all is good. ill make sure to keep posting all through my project.
Only the 4bl 1964 300cid had 11:1 compression (355 Wildcat)- not the 2bl. My guess is that it is due to different pistons, as the head and gasket part #'s are identical....
64 sky do you know if the combustion chamber size on the aluminium heads is the same as the iron heads. theoretically if you made more compression you could make more power then. in 65 wasnt the regular 4bbl 300 a 335 wildcat.
Dan, I know my 65' 300 is the 4 barrel hench the 355 Wildcat, the 2 barrel was the 310 Wildcat. Hope this helps! Doug
According to the NHRA, the 1964 Buick 300 heads had 50.14cc chambers (both 2bbl and 4bbl) and the 1965 300 had 51.12cc chambers (both 2bbl and 4bbl). The compression differences were accomplished by different piston dishes.
The chamber volume in my '64 heads came out to 52cc. Here is the link to the build: http://www.v8buick.com/showthread.php?t=160403 It's a bit more than you'll probably want to do but does show another approach. I expect it to run rather well, am shooting for an extended redline but moderate power and good driveability/economy. You'll see that for the most part it is a conservative build though as hitting a particular power:weight target was not considered a problem. As mentioned before, a set of the new TA heads (properly ported) could add much to the combination. If it was needed, which it is not. JB
Jim - I quickly read your build up (I had read it previously) and wondered how the flathead rods worked out, the rest of it seemed pretty straight forward (but I'm gona re-read it again). How is the build going any additional info you got I'd love to hear. Thanks, Doug
if you build a 300 as i am you can use the sbc LT1 small journal rods and the H beam versions are very cheap from eagle. I'm using those rods with GN forged pistons for my rotating assy. i doubt i'll notice the missing 40-50 cubic inches one bit.
GranSportSedan - 40 to 50 CI is quite a bit, you sure it won't be missed? I am really interested in your build. Doug
a turbocharged 231 V6 can make big power, why cant a 300 V8? take a short stroke big bore motor like the 300, add a set of good flowing heads and a good induction system and you have a recipe for a high winding smallblock. then add 6-8 psi boost and hang on. TA has my name on a list for the new 215-300-340 heads and when they are available i'll start a thread here on the board showing the entire project.
GranSportSedan It makes sense to me, I know its all in the combo you build up having quality parts and making sure all of them work well together. I'm just doing the pros and cons and the research between the 300, 340 and the 350 to try and determine the best bang for the buck, duribility and reliability. Doug
i'd look real hard at the 300-340 before the 350 in a 64-67 car. the 350 headers dont fit in the early cars because of the narrower frames in them. i'm building a 300 because it's what i already have and the short stroke intrigues me
GranSportSedan - I guess that is what I'll do as well (being in the same boat by having the 300). I was also wondering you know of anyone who tried to swap in one of the 3.8 Ltr Super Charged V6's? That could have some possibilities!! Doug
Doug Contact member sdslider hes in the process of doing that right now. you just have to remember alot of electrical for that motor.
