I know borderline fabrication fourm.

This started life as a square bore to spread bore adaptor but going the reverse I only found 2 options and they were total POS.
One was an open andthe other necked down into 4 very small holes.


I know flow is limited since the secondaries are kinda tight but I think it will work well enough. What do you think? I wanted to keep in dual plane fashion to keep tq up a tad.

Edelbrock does make a spreadbore RPM intake. I know because Apeiron has one. Maybe it would be easier to just get the right one and not have to fool around with spacers and carb to hood clearances ...

Yea I know but hood clearance wont be an issue on this application. I may eventually go back to a holley but I just like how smooth the Q-jet runs. I was looking for a spread bore RPM to begine with but this I got local and the store price matched and beat Jegs price by 5% not to mention no shipping fees.


Just think of it as a TruckMaro sincethats what my parents said I use to call it when I was 3.
