I have a 65' Skylark with a bone stock 300 2 bbl. I'm looking to find a 4 bbl and intake for it. Can you guys help me out with which motors have a compatible direct bolt-on 4 bbl intake? Will a 340 4 bbl intake fit? Thanks, Steve
If my numbers are right, you can shave 0.115" off (intake and/or heads) and get the Wilpower P76 single plane to fit. (Australian) Maybe. Or just use the factory 4bbl. Jim
the 215/Rover, 300 and 340 are all different deck heights. i've heard of using a 215 intake on the 300 but you have to fabricate a fairly large spacer between the head and block to make it work. the 64 300 has aluminum heads and intake but the runners are quite a bit narrower and most of the small block guys seem to recommend going with the 65-67 300 4v heads and intake.
Only the '65 cast iron 4 barrel intake will work correctly, though some have used the '64 aluminum one. There were no '66-'67 300-4 barrels, and the 340 intake is too wide. There are no bolt on aftermarket intakes, so you'll need to find a '65.
If you try to put a 215 sized intake onto a cast iron 300 head, you'll have a major port mismatch. Better to try and find the cast iron 1965 4bbl intake. Greg
There is a 65 4 in the for sale parts section,has carb and intake and looks like a buy for 275.00.The only one that will fit is the 65 cast iron one so Aaron is correct.I wanted to but the other one for sale but just cannot swing it financially right now but its a good price for a hard to find intake........Bruce.
Bruce, Yes!! I just noticed that you posted this above, thanks for that. I actually just happened to be strolling through the parts section and noticed it. Thanks, Steve
Here's the Wilpower single plane intake I mentioned. Seems like it'd be a good choice. http://au.geocities.com/p76cortina/P76_intakes.jpg Jim
I'm with Jim on the Wilpower intake. Shave the port side. Good idea, Jim. For the sake of lower RPM throttle response with a single plane I'd go with a smaller carb. Like Edelbrock's 500. Cool.
So far that's about all I have except for the parent site: http://au.geocities.com/p76cortina/P76intoTC.html Here's a link with some more info, showing a variety of intakes: http://www.mez.co.uk/ms12.html or you might try inquiring here: jrivett@ausfirst.com p76v8@yahoo.com Also this quote: " John Harcourt Engines 559 Springs Road Prebbleton Christchurch 8153 New Zealand Phone: 03 349-7263 Don't know the country code for New Zealand. He makes a nice single plane intake for the Buick\Rover and I think, a block girdle. He's the Dan LaGrou of NZ! If you talk to him, he knows his stuff! He's a P76 guru as well and makes adapter plated to fit a Buick\Rover intake onto the tall deck block." That's all I have right now. Jim Greg</pre>
Hi. The 65 Lesabre used the 300 V8. I believe it was the only engine available. You will have a better chance finding a 4 barrel intake on one of these in a wrecking yard rather than a Skylark. Good luck.
