Proof you can get 400+ hp out of a 4.6 2v NA
Remember my old thread about the Engine combo? Here it is to jog some memory.
https://mustangforums.com/m_3763557/tm.htm
Here is one of many sites that offer 400 hp NA 2v GT's.
http://www.seanhylandmotorsport.com/...-engines.shtml
400 HP 4.6 SOHC
Part No. SHM2V400
4.6 cast iron block, filled with a forged steel crankshaft, forged rods and 9.6-1 compression forged pistons. Ported Pi cylinder heads are fitted with oversize stainless valves and high performance beehive valve springs. A pair of billet camshafts, ground with our hot street cam grind provide a broad powerband and the lopey idle of a hot rod engine, Billet fuel rails, polished billet throttle body and cast aluminum valve covers complete this engine package.
$10,995.00
And Guess what? Thats without a Big Bore Block. and without FRPP heads which our better then PI heads. Any questions? With FRPP estimate another 30 hp, and with a big bore setup another 50 hp. Woot 480 hp 5.0 2v GT.

+$8,000 for the rear which will snap, a new tranny, wheels/tires to put it to the ground, and then all the suspension you'll need. After that you'll be set. Sounds great!

Crankshaft HP....Who cares...It's to the wheels that counts. Hell, my lil 283cid 2V puts over 450HP at the crank. I think people might have misunderstood your ? about having 400HP out of a 2V. It's not that difficult to build a 400HP 2V motor, it's getting that much HP to the wheels which is pretty much unheard of.

9.6:1 CR? Hm..seems you could bump it a bit if you tuned it to run 93. Maybe that's all they have in canada, eh?
While you can have a mean 400hp (crank) in NA form, it probably wouldn't be thatwell behaivedon the street.

Also it's nothing unusual for Sean Hyland to make claims they can't back up. You go to any NMRA or FFW event and you won't see their junk running there
