355 cfm ported and polished LT1 intake/TB

Just thought Id share some
May have this one converted for dist next week well see.
All ports and injector bungs were blocked off when flowed to give an honest real world #
No 8 really lags and needs more time than the rest.

Very impressive numbers. What is it going on? Would a mono-blade TB fit that?

Re: 355 cfm ported and polished LT1 intake/TB

Dont have anything to put it on just a hobby thing
Probably go on ebay I suppose. Dont want to make this a FS thread though (honestly it wouldnt be cheap)
Still waiting for TB gaskets and a TB top plate dont want to put that ugly black plastic one back on. Got a stainless bolt kit put together etc.

I have a carb on my old schooler so cant use.

Opening will take a 58mm TB dont know how the monos fit to be honest.

Ditto on the #8 cyl comment theres no radius for it to pull from. GM even oversized the port to compensate at least on the LT4 I measured sure this is no different. Just needed more work. bout overkill as it is sure it will feed a healthy motor

Uncovering the adjacent 2 ports only picked up 4-6 cfm so that reconfirms the lack of radius is the culprit not the port size itself. All ports and injector bungs were blocked off when it was done to be more accurate
See what happens with the next one!

Fun stuff.
