I am so full of questions and opinions today. Here is my situation:
I either want to build a potent 347 or 427(small block) in my 1966 mustang. The car is not a drag racer, it is a street cruiser. I have a built C4 with a TCI 3300 stall converter, a 9" rearend with aubrun 3.50 gears. I have a set of late model twisted wedge heads that flow 320/235. The guy I bought them from said they went 134 in the 1/4 on a stock bottom end 302 naturally aspirated. I also have 1.7 Cobra Roller Rockers.
Money is somewhat of an object, but i am about to make a killing selling my other car.
Benefits of having the 347:
I have a 4340 eagle crank already
a Prepped roller block
an msd pro billet carb dist
a 650 speed demon carb -however....
I am REALLY considering a complete weber setup....but i dont know how they would perform on this engine. -opinions on that please.
The cam will be custom ground by compcams. The other benefit of this engine is weight and I wont have to switch transmissions.
Drawbacks:
Strength of block
Benefits of the 427w:
Wow factor (I guess I can get that with the webers on a 347)
STRONG block and crank, no worries about putting high HP through it
Lots of torque
Drawbacks:
Id have to start collecting parts from scratch again.
Have to swap trans to handle that torque
Extra weight (nominal)
Clearance issues with Carb/intake/aircleaner
So...what would YOU do and why?
427w?
347 with webers?
347 with a demon carb?
