Who would have thought I would have some many problems figuring out a motor for this thing? I want boost!...but I want it to fit.

I want to convert my 65 to 331 with fuel injection but I don't know what intake will fit under the gt350 hood. I oringinally wanted a turbo but there is no room and the cost would be too much to justify it. So I am looking at superchargers. Anyone have an experience with aftermarket efi intakes and hood clearance in a 65-66?

Thanks. I searched the forum but couldn't find much about this. I would go carb too but the paxton guy says I have to use a dual plane intake to use their enclosure for blow through...and says if I don't use that enclosure, and use a carb hat instead, drivability is crap on the street. Is this true?

I have never had a car with boost. Help!

Sound like your talking to the wrong people. I have had both a Paxton and now have a turbo. If your worried about cost, then just back away from thinking this is a "cheap" mod.If you mill the carb base on a vic jr. it will fit under a stock hood, but a Edelbrock RPM is better.As far as drivability, that depends on your tune.I went from a carb to Powerjection III fuel injection with my turbo and the car will start and idle like my 06 is runs smoother then ever.

I run a Paxton with the Edelbrock Pro-Flo efi setup. I have no hood issues with a lower profile bonnet, with my gt350 scoop.

Thanks for the replies. I have quite a while to figure this out but I like to have a good idea going in what I will need because I hate buying parts more than once.

I agree that perhaps I have talked to the wrong people but I know full well that this is not a "cheap" hobby. However, with the quotes I have gotten for a custom turbo, the cost just didn't seem to justify the novelty of having a turbo vs. a supercharged combo. The quotes have been upwards of 3 times the cost of a blowthrough system (if I can make a blowthrough work). Keep in mind that this will be the first forced induction combo I have ever run on any car, so I am sort of flying blind here.

I talked directly to Paxton/Vortec and was told that the victor jr would not fit with the GT350 hood. So, if by milling the intake it will fit, that is great news. I was also told that the carb enclosure that Paxton uses is FAR superior to a carb hat on the street and I simply have no experience with this. Is this the case? If I use a Vic Jr, how much would have to be milled assuming I am using TCP drop motor mounts (about half an inch)?

Both rides are very nice. I have never thought about using a Retrotek or Edelbrock efi system. Any issues with tuning on either?

Thanks again for the replies.

Not to hijack, but I am wondering the same info. I have a 331 w/S-trim in my 95 coupe and was curious if my Performer RPM EFI intake would fit under the stock 66 hood?

nice thing about the retrotek is it looks just like a carb.

I have the Edlebrock Performer EFI and it fits. It is very close to the hood but but it works. My other issue I had was the V brace. I tried a couple different brands, but ended up making my own to fit. I have heard that the GT40 intake with a little porting is a great intake especially for the money!

I have the paxton supercharger on my 331 with a vic jr and a carbhat.

Decided not to use the carb enclosure !

With a low style carb hat i didnt have to mill anything from the intake to make it fit.

Its a squize but its working.



The most work was the dyno tuning, everything is good now and it has loads of torque ! A blast to drive !
