how can I get 300hp from a 64 300? does a 215 intake fit with spacers? where do you get the spacers, and how do you deal with the water ports and the lifter valley. This is going into a model a ford so would like to maybe build my own intake for 2 2bbls or get something odd so the chevy boys will really be baffled as to what the damned thing is and hows it run! :3gears: :3gears:
You can get a stock 4bbl intake for a '64 300, it is aluminum and someone on this site may have one they can sell you and they also come up on eBay now and again. As I recall there is a company in Australia that sells the spacers to put the 215 intake on the 300 but I can't remember who they are. You could make your own plates out of aluminum stock, I believe I saw once on this site how thick they need to be made, do a search and you should find it. '64 was the only year that the heads were aluminum, the intake ports are smaller than the later '65-'67 cast iron heads so the '64 heads and intake probably don't flow as well as the later heads would. I'm not an expert on the 300 but I know that there are those on this site that are. The way I see it, from what I have read (someone please correct me if I am wrong) the limiting factor to make alot of hp with the 300 is the heads. They are carry overs from the 215 and do have larger ports but not as large as the 350 heads, the 300 valves are smaller (smaller engine) compared to the 350's as well. The 300 heads can be ported and you should be able to install larger valves but I am unaware has to how much more ponies that would add. To get 300hp from a 300 you would need a cam change for sure and higher compression like 10ish:1 as well as some head porting. Not to jack your thread, but something that has been in the back of my mind is to build (who knows when, if ever) a turbocharged, intercooled EFI 300 based engine. I would have to get custom pistons or bore the block .050 and use available 231 pistons, wanted to use 350 heads as they have bigger ports and valves already. I don't know for sure if the 350 heads will bolt to the 300 block but I suspect they do. A custom intake would be a must, but could be built at home from exhaust tubing, knowing the whereabouts of a mandrel bender may be an asset as well. A custom grind cam would also be needed as the 350 head valve arrangement is different than the 215,300,340 engines. I know that I haven't given you any specific answers, but if you do a search on this site you can probably find the answers to alot of your questions. Regards, Greg
Do a search. plenty of info, and it is an uphill battle..... BuickCityPsycho is the king of 300's. I'll trade a 300 4-v intake for a TPI....
I looked at a Alum head/intake 300 in Victoria BC, I'll try to dig up the phone #. The 64 4bb intake only fits the alum hesds from what I understand. The 300 is a great motor but even more neglected by the aftermarket than the Buick 350.
300 After reading all this does anyone really know if the 64 aluminum intake will bolt up and work on a steel head 67 300 ? o No:
Turbocharger manifolds that fit a Buick 300. About $800... http://www.chevroletls1.com/rover_v8.html Greg
I don't know for sure if the 350 heads will bolt to the 300 block but I suspect they do. they'll probably bolt up but your cam and intake won't be any good then. the 350 swaps valve order from the 340/300/215. if you look closely you'll notice that the center exhaust runners of the 350 are siamesed where on the earlier engines it's the intake runners that adjoin each other.
If you can get some spacers fabbed up, there are a lot of 215 intakes you can use. However, as has been mentioned, the ports are smaller on the 215. Here's a cutie for a 215 that's as rare as hens teeth: Dan Jones has a gallery of a lot of 215 style intakes: http://www.bacomatic.org/gallery/album13 Greg
a huffacker is what i adapted for my 300. the ports on it are already 300 size. 1/2" plate sides and 1/4" valley cover. the second intake in the above posted gallery is a huffacker
thanks for the info this little engine is going into a model a pickup with 2004r and 355 gears so should be snappy and economical too. I think I may try to build an intake for multiple carbs for "thelook" but will install a 4bbl for the time being. TPI for the intake and a cam? also can you get header flanges for these or are they really worth it? the manifolds look pretty good.
Heres a 300 4 barell Intake on Ebay for a 64 ! :Brow: You won't see too many like this one ! :Brow: :3gears: :Brow: :3gears:
Look at the price the one on ebay went for. I think you shoud offer me YOUR manifold and a cam for mine. Especially since I gave you the whole engine to begin with! :spank: :rant:
whoever is bidding on that one on e-bay is nuts,:spank: the last one I watched went for 65.00 with carb!o No: I seem to remember giving a 430 and a 64 skylark away some years ago and I think it had a 4bbl 300 in it!
Ha, :Smarty: you gave or sold the 2-bbl 300 to Tony Tillo and I paid for the Skylark, GS shell, & engine! (which was given to you by our mother) Your memory is going with age..:moonu:
In the now infamous words of our national savior uncle ron " I dont Recall" :Smarty: age does have its advatages, when your my age you'll find out! If you want the tuned port its yours I dont need it for anything and dont plan on getting a sbc anytime soon
What made the most difference in performance for my 67 skylark with the 300 2 bbl. was my tranny swap. I put in a 200-4r from an 87 monte carlo ss. It was like adding an easy 60 horsepower and I will get tremendous fuel economy now. Under 500 bucks for all I needed. If I want to go faster I can swap the gears in the rear end. I do not intend on trying to build up the motor because of the lack of performance parts. Only thing I've found lately was headers on ebay for 475.00.
Now I just need to figure out where to relocate the front suspension and the steering column....:laugh: :laugh:
I recently paid $250 for a set of 64 aluminum heads. That was a very good deal. But here's the catch: they aren't all the same. Many of them have a bunch of threads hogged out in them, due to people treating them like iron heads. Many have poor spark plug hole threads. I found a guy who had several pairs of them, and the two I bought were the only ones he had that were salvageable. The spark plug inserts for iron heads won't stay put in the aluminum heads.....ask me how I know. :spank: If you really are going to buy a set, make sure you take a good look at them first. IMHO, stripped spark plug threads = a useless head. Nobody wants to re-weld them and fix them anymore- it seems that the industry is losing all the expertise it once had out there.
