Yes, that is correct. Although I may have used a shorter filter, like a 2.5"

Here is the scoop. I mocked up the engines today, The big block Chevy (std deck height) with the LS6 intake, according to my calculations and measurements, is 1/4 inch lower at the carb pad than the small block Chevy with the L79 intake. Given both engines mounted in the same place. Of course variations could occur from sagged body mounts, crushed engine mounts, etc. etc. Your results may be different, but I think I am fairly close here. Now if Dan is checking in on this thread, could you tell us about how much clearance there is above the air cleaner lid and hood. Assuming a GM HP drop base air cleaner and 3 inch element. This would be on the 1957 car jrm5657 referred to that I believe he said you have with the L79 intake. Thanks to Dr L88, jrm5657 and all for your help in figuring this out. It was this thread that got my interest rekindled in this "project creep" 1957 of mine. Knowing I can get the bbc in it has really got me going again. I will be posting results in a new thread, as I feel like I have hi jacked this one, and that was never my intent. Since we all like pictures, I have included a couple of the intended engine for my C1. If you look closely you can see the air cleaner base sits so low the breather tube actually hits the valve cover! Thanks again to all for your help.

That is a nice looking rat. I guess you are planning to use a front motor mount plate of some sort to keep as much exhaust clearance as possible on the sides. A BBC is an inch or 2 longer than a SBC I think, but I don't think anything would interfere up front around crossmember or steering. Probably won't be able to use a mechanical fuel pump with out notching the frame rail because SBC fuel pump is a tight fit.

I'm hoping to use side mounts, since I went to R & P steering there is extra room where the steering box was. Just have to run u joints and shafts around the #1 tube. If I can go side mounts that will allow me more options for engines in the future if the bbc doesn't work out. Fuel pump is no problem as it's a Gen V block w/o fuel pump boss. I'll just have to mock it all up and see how it goes. If push comes to shove I can always go with front mounts. Big thing is on top, I won't cut the hood, and I think I am past that. Thanks for your help.

I have a 61 and want to put a 396 into it...had one in high school, 425hp. Used a Bill Thomas kit and it dropped right in,,,didn't have to cut the hood and the headers fit fine as long as you mounted them before installing the motor. I have contacted the guys @ Bill Thomas and they do not have any kits nor did they have any prints to manufacture the components. As I remember they were really hesitant to sell the kit but did. Car ran like a demon as long as you didn't want to stop quickly or turn a corner as speed. If anyone out there has a set up they want to sell please let me know. BK

I ran a Wieand 7530 Team G under my stock 62 hood on its 327 engine with a L88 Style GM drop base air cleaner.

I don't want to sell mine at the moment, but if you PM me your address I will make pattern copies and you can make some out of steel plate as I did. I copies the Bill Thomas pattern from ones a friend had, so you would be getting a copy of a copy, but should be pretty close. LOL
