Installed a HIF44 on a new Maniflow intake and now the base of the carb interferes with the brake lines below the speedo opening on the firewall. Probably would work ok on a 998 block but not on the taller 1275 A+. I think I may be able to get enough room if I don’t use the 1/2” spacer between the carb and inlet. Anything drawbacks to bolting the carb directly to the intake, not using the spacer?

The throttle mechanism hitting the manifold.

Use an adjustable engine steady to tilt the engine forward Or change the subframe to the later one that moves the engine forward 1/2”

I've heard about tilting the engine forward.  Does that affect shift linkage alignment or wear on engine mounts?

well it is that or re drill the subframe. people have been doing it for years. your biggest issue is the exhaust.

On second thought, I’ll stick with the mini spares inlet.
Thanks all for the replies.

I had to do this and a word of caution if you use an 'ultmate engine steady' type thing to push the engine forwards - if you don't re-enforce the studs on the bulkhead, it'll fatigue and fracture the metal around them. Mine did it and I've since read of it happening elsewhere too. I now have extra steel plates on either side of the panel.

 

 

Not having a spacer between the carb and the manifold does cause the mechanism to foul but it doesn't take much fettling to make enough room for everything to move around without issue.
