Not sure why pictures would make any difference. It would look like a 305 TPI, or 350 TPI, or a 383 TPI, or...

Here's what you can do: Go back to the Engine Swap forum page. Near the top on the blue line is "Search This Forum". Click on that, then "Advanced search" at that bottom of that subwindow. From there, on the left enter "400 TPI" in the search text box, then below that in the pull-down window select "thread topics only". Then click on "Search". About a page' worth of hits will show up. Read to your heart's content.

My neighbor has a 406, TPI, technically has the Super Ram, but... it looks exactly like a 305, with a super ram...

Re: 400 TPI

the 400 with a TPI would be an awesome torque monster. I have always wanted to build one of these but never got around to it. It will physically bolt together but you will definately have to have a custom chip burned. This motor won't rev very high at all but it will surprise you where you need it.

Re: 400 TPI

Check out this article where they compared different TPI intakes on a 383 with TFS heads and aggressive cam. Stock intake only really feeds enough air on a 305. You can see power gains from article with intakes that flow more than stock.

I'm going to build a 420 sbc with a FIRST TPI intake.
