Power Boost?
#1
I know this has been addressed and I have been reading up on it, but the more I read, the more confused I get. Here's the deal. I am inheriting my grandfathers Mach 1 351 2V that he bought new in '73. It is completely bone stock except for Flowmasters he had installed before he passed. I want to wake the engine up a little but without making any mods that would prevent me from returning to stock in the future. I'm shooting for around 300 HP if possible. Is an intake and 4bbl along with a mild cam worth investigating? Open to suggestions. I'm not very well versed in this, so I'm trying to learn. Just want to wake it up a bit on a average budget.

Welcome from Iowa. You can get a decent increase in power with a mild cam, 4bbl intake, carb, and I would add headers as well. The more you pump into the engine the more you need to be able to pump out. Another huge factor in that "seat of pants" feeling is the rear gear ratio. What rear gears are you running now. What trans is in the car?

73 Grandé H Code. Headman long tube headers, T-5 Transmission, 3.70 Traclok, Lowered 1" all around, Aussie 2v heads w/ 2.19 intake, 1.71 exhaust, screw in studs, full roller cam 608/612 lift 280/281 duration LSA 112, Quick Fuel 750 CFM double pumper, AirGap intake.

Sorry, not sure of the gear ratio, but it seems to be more for highway that street racing. lol. The trans is an auto 3 speed I believe. Thanks for the reply. Sorry I am not very knowledgeable, but that's why I'm here.

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

There should be a tag on the drivers door. This will tell you what trans, Likely an FMX being a 351c from 1973 as well as the rear gear ratio interior and exterior color, etc. If you post a pic we can certainly help decode that info for you or you can go the mustang data tab at the top and click on 73 mustang info as well.

Thanks for the tips. I'll get a pic of the tag. I'm in southern middle TN between Nashville and Chattanooga.

If I were going to do a little power boosting on a 2 barrel engine, I'd use the parts below.

Summit 600 CFM vacuum secondary carburetor - https://www.summitracing.com/parts/sum-m.../overview/
Edelbrock Performer intake - https://www.summitracing.com/parts/edl-2.../make/ford
Hooker Cometitiion headers - https://www.summitracing.com/parts/hok-6921hkr
Lunati 351CJ cam - https://www.summitracing.com/parts/lun-10321004

I like this combo for this application as well. Especially since the owner mentioned highway gears (read as prob a 2.75 open) this cam should certainly help with the low end. Maybe add a Pertronix II for an easy upgrade to the ignition as well.

I am also on a journey to boost performance. I already run a 4v carb, so my first step is to install a 3.73 posi. that work should be finished next week. I will see how the new gear feels. if I feel fast enough, I may be done. But, I may have a lifter issue, which means opening the engine. when that happens, I may go with new heads and intake, but that is a slippery slope....when a new top-end turns into a bottom end rebuild, then you start thinking that a crate motor is cheaper.....so for me, its 1 step at a time.
