I was wondering if anyone here has bored out there 350TBI spacer so they could run a 454 TBI? I don't wanna bore my Edelbrock Performer TBI intake out..so would that work?

thanks

doubt it would do much good. you still have the bottleneck at the intake

I agree. No pointin a bigger TB if you're still going through the restrictor. It's just moving the restriction and adding more turbulance than if you used a stock "flush mount" TB unit.

 

I agree as well. I had my Edelbrock TBI intake bored to match my 454 TBI.

 

Me too, I had the TBI manifold AND the Spacer bored to 2". Pulls stong to 6,000.............bob
