- 72 Mustang Grande / 351 Clev. 2V + Weiand XCelerator intake + Holley 600 CFM carb
Hello guys, my Mustang is a Q code Grande but the original 351C CJ 4V motor has unfortunately been swapped long time ago, for a stock 1972 351C 2V motor coming from a Ranchero. Transmission came with, original FMX has been replaced by a C4.
Since one year I own the car, I tried to improve the performances of the motor by doing the following :
- new long tube headers (Hooker Comp)
- new 2,5" Pypes dual exhaust with x-pipe
- new aluminium Weiand single plane intake and Holley 600 CFM four barrel carb
Now it's not the fastest car on earth but it drives good, especially between 2800 and 4500 RPM with the 3.25:1 axle.
I think this combo provides around 240-250 hp at the wheels when tuned right.
Here's a video of me driving around :

Question is : I'd like to increase its power, my goal is something like 350 hp at the wheels. Is this possible ?
I think this car would be fun to drive with such a motor.
Conditions are :
- I need to keep the 2V heads because I don't want to get rid of my actual exhaust and headers ; or maybe getting aussie heads that provide same exhaust port size ??
- my motor is 40 years old so I'll have to replace the worn out parts.
- the new motor needs to be streetable and has to provide good torque @ low RPMs, and good top end too of course.
My thoughts about this is that it' will be no problem but I can't figure how much it may cost ?? I read somewhere that just a hotter cam and different intake will do the job, but if I go for such an upgrade, I want the new motor to be reliable and will for sure replace all the used parts in it.
I'm trying to list the parts I'll need :
- hotter cam kit, which one ?
- improved valve train, which parts ?
- forged pistons and rods ? Is it vital for reliability ?
- good electronic ignition ? which one ?
- bigger oil pan and pump ? which one ?
- new intake ? I thought about the famous dual plane Edelbrock Air Gap
- bigger carb ? Or maybe keeping the Holley 4150...
- 3.50:1 axle ratio switch ? Not sur about that. 3.25 sounds good to me already.
What's your opinion on this ? How can I improve my H code motor ?
How much do you think it can cost for just the parts ?
Thanks !
