fuel injecton for my 69 caddy convertible

[thebigman]

ok this is all new to me
i am asking if anyone has ever used a holley fuel injection system on a older 69-70 472 for my 69 deville convertible
i have buddy that insists that the fuel injection with a turbo charger is the ultimate set up instead of a complete re-build with a bds blower(i like the old school technology) and i think he is crazy, so if anybody has any ideas please reply, this is our first cadillac project so i am turning to the experts on this one during the planning stages
thanks in advance for you help

hey bigman,
this is the Gsopel according to DOC: bling, BDS. power, function, and drivability, turbos and injection.

EFI is OK, not sure about the Holley units. From what I've heard, biggest problem is getting the injectors sized right with any add on system.

The GM systems (from late 70's early 80's ?) are best for the Cad.

This is all TBI too. For multiport, it's a whole nuther problem.


I remeber readin about tubro charging on the old board. Some problm with a getting a large enough unit to be effective? The 472/500 is a lot of inches for a turbo. Most units are for smaller engines, like 4 bangers. Seams superchargers were the better way to go. Thay are sied for bigger engines.

Then again, I may not remember any thing correctly

thanks for the info guys
i have contacted "mts" about possibly building me a motor
for the new bds blower packages finally they have a manifold for a 472
i was starting to feel like a red headed stepchild on caddy motors
i couldnt find anything until i ran across mts

now if i can just make it fit on my 69 convertible and find a new hood to cut into ha ha

hey do either of you guys know where i can find the specs on a stock caddy th-400 transmission i need to find out what my stocker will take as far as hp and torque i guess with a blown 472 ill need to tighten it up a bit
i am not having any luck finding the info
thanks

I have a pro-jection 2D. will this work on a '70 472 motor?
