1994 Cobra: Big Bore 347 Engine Build Update

It is hard to believe that the last time I wrote about the Big Bore 347 build was November of 2017.  But yes, it really was that long ago!  Things are moving along again now that I pumped some additional funds into the motor.  There have been some other changes also!  I thought it would be a good idea to outline those.  The 94 GT is for sale since we've picked up a 94 Cobra.  The 94 Cobra is where the engine will eventually find a home.  I've built a pretty stout 8.8 rear - read about it in another blog post.  And the TKO500 will be the transmission.

Block is a Dart SHP, bored to 4.120.
Rotating assembly:  Probe crank, CP Billet Rods and Pistons. Looking for 10.5:1 Compression.
Heads - AFR 185s, resurfaced and ported.  LGM shaft mount rockers, PAC racing springs
Cam - Custom grind by FTI
Balancer - Romac Gold, 28oz

The rotating assembly is being balanced, and the head work is in progress.  Once that is done the final assembly will begin.  Before I take delivery, it will be broken in on the dyno!  I was told this should make around 460 on the engine dyno.  I'm hopeful!
