I was thinking about getting the mini-ram 3 and vortec heads for my 305. It's supposed to have the 350 cam 207/213, 5 speed and edelbrock headers. Would this mod be alright until i can afford a new 350 or possibly adding a supercharger to combo above.

 

I called tpis & they told me that it would be to much airflow for a 305. SO they wouldn't even sell it to me.

 

Hmmm. That's interesting. You can put a carb on a 305. Rot-jets were upwards of 750 CFM. It would seem to me that the small head passages would maintain adequate velocity for torque. I wonder why it wouldn't work, especially if you kept the 48mm TB? I don't know why anyone would want to, but why not?

 

You may as well change to a bigger and better cam.

Just because nobody has tried it doesn't mean it can't be done...

 

I am determined to make my 305 chew up the 350's. I just want to prove that they have way more potential. I want to be able to say yup i just beat you silly with a 305! hmmm I need a lot more money!

 

You know, I have a Miniram sitting in the basement and a 305 sitting in my car. Since the 385 engine wont be done in time for next spring, it might make an interesting academic excercise to strap it onto my existing motor, would it not??

Maybe I could even tune up a #730 speed-density chip for it.

Does anyone have a spare set of 19 pound to 22-pound injectors laying around that I could have? My miniram is loaded with a 58mm throttle body and 30# injectors which I KNOW are too big!

Dan, you can have my stock 22 lb injectors for the price of shipping them to you. They probably need to be cleaned and flowed though.

 

WS6, given that the Miniram is so easy to install due to it's one piece design, I think it would be an interesting experiment.

Definitely, tuning that Miniram would be key to how it performs. But it would be interesting to see how well (or poorly) a Miniram DOES perform on a 305. What do you care, cause ultimately you will be going 383, and the Miniram will be easy to remove. Also, you will have a "base" VE table that will be closer to what you need ultimately for a 383. With SD, the "shape" of the VE tables are critical and a Miniram has much different VE table shape than TPI.

Also, getting setup is not a bad idea when the "steps" are smaller. The biggest problem guys have when they decide to get into PROM Burning is they wait until they NEED that prom. They should begin even if it is a stocker. If you are going SD, do it now while you can get a TPI BIN that is basically correct and just needs tweaking. Then, after you have "mastered" tweaking your TPI BIN, move on to the Miniram BIN for the 305. Lastly, the 383.

By the time you are at the 383 stage, you will know basically all you need to know at that time and find the tuning quite easy. Wait until the last minute, and you'll be so overwhelmed and so "green" that you might find it frustrating.

See you at the DIY PROM Board if you go for it.
