2009年4月1日 · Hi the question is: what are the differences between 1971~1973 351C-2V engine and 1971~1973 351C-4V engine except intake manifold and carburetor. is it possible to conver 351C-2V to 351C-4V? Do they use the same block? Thx

2009年6月19日 · About 20 years ago a guy I know bought a boss 351 Mustang. It was a dog at all speeds below 4000 RPm.. I got some 2 V heads, ported them quite a bit, and with a matching Edelbrock 2 V intake, the car PICKUP 7 to 8 tenths of a second , …

2013年4月21日 · I have the same situation now check this out - the 4v head and the 2v heads are different 4 v heads have a bigger port- intake and exhaust -BUT you can put a 4bbl carb on a 2v block with an intake set up for 2v heads ebay and also adhunter have them at times I just got one .

2011年8月1日 · Re: 351 cleveland 2v Combo Here's a 351C-2V combination that will run on premium 91 pump gas (9.2 compression) I developed over 20 years ago but looking back, it was a superbly balanced street performance set-up and a real blast to drive in the 73 Mustang I had at the time. Block: Bored 0.030, set-up for 0.0025 clearance to L2379 TRW pistons.

2009年6月6日 · No - no US closed chamber 2V heads. All are open. The only closed chamber "2V" type heads are Australian 302C heads. The "2" was used on 351C engines as far as we can tell and no number was used on 351M and 400 heads of the same type. Any they may have dropped the 2 on later model heads.

2004年9月12日 · I recently removed my mild 351c with openchamber heads, 9.4:1 comp, hydraulic cam, weiand 2v manifold and a 850 Barry Grant. It made 226 hp at the wheels, but now i'm waiting on machine work, and will soon have results for my new motor with solid cam and AFD alloy 2v heads. If i could work...

2010年1月3日 · I've ported a couple of sets of the Aussie closed chamber 2V heads. The only closed chamber 2V heads are the Aussie units, and the valves are HEAVILY shrouded, and need major unshrouding work to flow good numbers... even with stock sized valves. Installing larger valves would surely hurt flow big time if there wasn't some major unshrouding work ...

2010年10月2日 · From what I see 2v, 4v headers are different. What exactly are the differences? I have a 351c 2v with headers (hooker I think) I plan on upgrading the heads to 4v Open Chamber CJ's. Can I modify the 2v headers for the 4v heads? Would be nice because i KNOW these will fit past gear box, trans etc. Feedback please

2011年5月24日 · I got looking at some of the older 351C cam profiles and sow some with pretty high numbers. The 1971 4v cj hydrolic cam looked pretty good at 270&290 with 490 lift and 46% overlap. And the 351C boss cam looked pretty dam good at 290&290 with 477 lift, but it was a mechanicle cam and needs adjustable rocker arms so the boss one wont work for me.
