hey man buy the time you do a 330 on roids you could buy a used Procharger off the board!Take my word for it Ive done several.....To do it right you need heads, exhaust,ignition, carb , intake, roller rockers, and a rebuild kit, with all that your better of saving for the Charger...my .02

For most people, it would probably be better to spend a little more and get the Procharger. But for me, I think my plan is better because I already have most of the parts needed. As I stated in my first post, I have a buyer for my MPI. Total cash outlay will be under $500.
No one has answered either of my first two questions.
1. Is this a good idea to swap the MPI for a carb?
2. Will I actually gain any RPM or speed from these mods?

with out changing the heads I think your better of leaving it alone.......go with a holley 800 carb if you switch my .02

if you do a search on" 300's on roids" you can see what I did a couple years ago...proven package with lots of Hp (505) lots of input from Kaama,Crazyhorse and Bruce and other Motor guys!!!

Thanks Dyno!
I will check it out!

I currently have VORTEC heads. Aren`t these supposed to be good mild-performance heads?

you better ask JimV about those heads....I've never heard that anyone was having any good #'s from the stock heads!!!

In answer to your two questions:

I feel that the MPI will hold you back from more power. It still works in a supercharged setup because they all have fuel enrichment capabilities but that does not apply to your setup so I think you are doing the right thing.

As far as RPM/Speed you will change/move the power band up with a cam change but be careful to not go over 5000 rpm with that motor because it will come apart. As far as speed increases go you can expect about 1 mph for every 20 hp increase on a Baja.

Also don't make the mistake of over carbing that motor.

Hope this helps !!!!!

SuperV turns his 330's to 5700 never came appart yet! 7 years and counting!!!!good machine work is the key!!!

Ask Brad Perry ,pm or e-mail him, He has a recipe that will gain you 7-10 mph and yes it does include a carb
