    Change driveshaft length going from FMX to C4?

    I heard their heavy and cause alot of power loss to the rear wheels. I'd rather stay with it but seems everyones been telling me to go to a c4. Maybe i'll just install a shift kit and higher stall on the FMX. It's 30 years old I dont know how it will handle 375HP or so. When I pull the trans...

    Whats everyone favorite year classic mustang

    Im starting to like the 71-73 Mach 1's alot more since I got one. They have that big muscle car agressive stance in par with the GTO's, roadrunners, and Chargers of the day. Throw in the blackout hood, mag 500's, lots of rubber, and spoilers :banana: But don't get me wrong im a fan of most...

    FMX to C6 swap?

    Thanks for the reply's The only reason I was planning on swapping is I hear alot of crap about them, people saying how bad they were and a few told me that it would fall apart the first time I ran it at the track. Usually the first thing I hear after I say I have an FMX is dump that thing. I...

    FMX to C6 swap?

    Has anyone ever done a FMX to C6 swap? Is this the route to go if IM planning a 400+HP 351c 4v build? I have a chance to buy a c6 with 5k miles on it, the tranny has a shift kit and a tranny kit. He said it was always used as a street car daily driver and never raced. Is there alot involved...

    Edelbrock torker intakes?

    Has anyone used the Edelbrock Torker intake? I been thinking about using one if I go to the 351c 4bbl, are they any good for a street car, good HP and torque over stock or should I go to a blue thunder instead? Thanks, Jim

    How do the aussie heads stack up against....

    Could anyone tell me how the Aussie heads stack up against the 4v American heads? Also what kinna HP increase would I be looking at over the stock American 2v heads going to Aussie heads. Can the Aussie heads ever create the power that the 4v American heads can? Thanks, Jim

    351c 4bbl open chambered heads any good?

    What would I have to change to go to a solid lifter cam and are the titanium rockers and screw in studs necessary? Would a setup like this pull hard off the line? Thanks for the reply, Jim

    351c 4bbl open chambered heads any good?

    The 4bbl open chamber heads have something like 60-70HP over the 2bbl heads? I think the 72' 351c 2bbl was 177HP, the 4bbl open heads were something like 250HP? Would I gain all this power by going to 4bbl heads? As for torque will a 2bbl engine take off much quicker and have a faster 60 foot...
