Hello all,
I am starting to work on my 1973 sportroof again and have a few questions? I am rebuilding the 351C 2v and looking for ideas. I want to build it for street not really going to take it on the freeway. I have 2 choices for distributors, a Mollory Unilite vac advance or an Accel Pro mechanical advance. I also have 2 carb choices, Edelbrock 750cfm or 625cfm. Formula says 625 but I plan to use an aggressive cam. I am going to change out the rear end should I go with the 3.91:1 or 3.73:1. Planning on driving it a lot not just a weekend warrior.

 

id go with the 3.91 and put a 5 speed or aod in it.

 

gears will be dependent on cam choice and torqe converter if auto ask the cam company the spec id definitely go with a vaccum advanced dizzy and id use the 750cfm carb. also check out www.ausfordparts.com and check out the intakes and heads etc

 

Thanks for your help. I will go with the 750cfm and the Mallory Unilite. I haven't picked a cam yet. The current torque converter is stock. Parts thatI already have are; Edelbrock Performer intake, Wieand water pump, headers, MSD 6a, Comp springs on 2v heads and a double roller timing gear set from Comp Cams.

I read in a magazine a long time ago "The 3.91:1 Traction Lok because you didn't just want to beat the niehborhood kid in his Camaro you had to humiliate him." Every since then I wanted the 3.91.

Nothing against new technology but I want to stay with old school because I am going with a retro look.

 

i agree on the gearing and dizzy for what your wanting to do, but i'd use the smaller carb

 

Use this calculator to determine carb CFM.

well you can get some aussie heads off of the ausford site and still look stock are you gonna be running 2v or 4v heads? id defintely get a converter

 

I am going to use my 2v heads. What would redline be on a 351C? I am going to do the trans and stall converter next summer. I want to get it out this year and drive a bit because it hasn't been on the road since June 1999.

 

depends largely on cam choice also but the factory oil system is good for about 7 grand i believe as long as the valve springs are up to the task etc but if i was u id look into the external oil mod where you run an oil line from the oil pressure fitting in the front to the one in the rear

 

I like it! Nice ride! Just lose those chrome wagon wheel rims.

Nothing else to add sorry.
