The rotating assembly is zero-balanced prior to assemble. The Probe 14427 piston will yeild 13.7:1 compression with the 58cc chamber RHS cylinder heads.		TMeyer blocks come with high-quality ARP head bolts as part of the deal, however for this application Tim opted to replace them with ARP head studs.
The TMeyer block comes with four bolt mains and steel billet main caps. A new cast block with these accoutrements for $1599 is quite a deal.		For this engine Tim worked with Ultradyne to spec out a solid lifter, flat tappett cam with 263/267 duration and 639/619 lift on the intake and exhaust side respectively. Tim's view is this is a conservative cam that will prolong the life of this type of motor.
Porting iron heads is a laborious task that is quickly becoming a lost art due to the prevelance of aluminum heads. Consequently you can expect to pay $1200 to have these RHS 215cc iron ported to the hilt by TMeyer. The results are well worth it, see below.		As with most professional cylinder head porters, TMeyer prefers buying their heads bare and then assembling with hardware and valvetrain components to match the needs of the motor. These heads get fitted with fairly common Manley valves and dual-springs as spec'd by Ultradyne for the chosen cam.

Dyno Results
At the time of this article Tim Meyer has the assembled Ford 454 loaded on his engine dyno and broken-in. While this engine will run alcohol at the race track, the initial dyno tests were performed with gasoline. The engine belted out over 625 horsepower and 600 ft.lbs. of torque! Tim expects another 20 horsepower increase with alcohol. We'll bring you that dyno result when it becomes available.


UPDATE
Tim Meyer informs us that dyno testing of the 454 stroker IMCA motor on alcohol resulted in a monsterous 650 horsepower and 659 ft.lbs. of torque. The video below gives a taste of the crisp and thunderous sound resulting from a well-built Ford stroker engine.
