1996 LT1 air filter to intake routing

I'm putting an LT1 into a 38 Chevy with limited space for routing air into the intake. I've seen pictures of similar installations where the air filter is very close to the intake with essentially no ducting between the two. I'm concerned about how this arrangement effects the MAF sensor operation, as well as any other concerns I may need to allow for with such a short run from filter to intake. Any info or suggestions are welcomed with gratitude.

Lt1

I ran a very short intake on my 33 Willys with no problems. As I remember it the temp sensor was in the filter and the MAP sensor was disconnected from the top of the intake and connected to the intake via a rubber tube. The MAP lived in the valley where I just wedged it in. Did this because I used a S & P chrome intake cover and 'Vette valley covers.

Thanks for the reply, 39 Master. Beautiful engine bay you have there! Were you able to squeeze the MAF sensor between the filter and the intake? I think the MAP sensor you refer to is a different item In the stock configuration (98 Caprice) the MAF sensor is in the ducting between the filter and the intake pretty far downstream from the filter. I was just concerned about smooth airflow so close to the filter, but it sounds like it's working for you.

I had an early LT1 and didn't use the MAF, just ran it on the MAP as stated earlier. Your engine bay and mine are about the same with nowhere to go for fresh air. The short intake didn't seem to hamper things, got 22 MPH on trips and ran 13.0 @ 104 MPH. Present ride is a '39 Chevy with an LS and a MAF/MAP system. There was some concern regarding the air flow but I made the intake tube bend back over the engine with a straight shot over the MAF.

Thanks again for responding. The "bend back" over the intake was suggested to me by someone, but I was thinking what you did with the Willys was cleaner if the disturbed airflow was not a problem. Sounds like you had the same concern with the MAF. It'll be awhile before I'm ready to plumb it, so I guess I'll see what I can fit. Have you known of anyone using the MAF with the direct routing like you have on the Willys?

Air intake

Have you looked into just running a MAP and dropping the MAF? I'm getting old and really don't NEED lots of HP or getting every ounce out of an engine. Sort of a balance between form and function. Here is my '39 intake...ugly ain't it?

Definitely not as pretty as the Willys! I'm still a ways off from plumbing it all up. I like the clean appearance of the Willys setup, but do want to retain the MAF. Have you known anyone who used the MAF in the more direct straight in configuration?

Most people have moved on from the LT1, but hey it served me well and I like them. Got a real challenge on your hands. Can't say as I can help much...sorry.
