torker 2 is great for the price...there sure are better intakes but for the money you cant beat it....my .02Siggy_Freud said:There are a lot better intakes than the Torker 2. Look at a few of the others on the edelbrock line and just do some general research online.

Put the 400 heads on the 350 and change the cam you should be good to go and save a lot of effort. Then take your time and build the 400 into a monster.
jimfulco said:Make sure the 400 block has the same holes for the motor mounts that the 350 does. Pontiac used two different bolt patterns, and not all will interchange without adapters. Some have both patterns, so you might get lucky.
400's & 350's have the same stroke, 3.75". Pontiac crankshaft flanges changed a couple of times in the '60s & '70s, so be sure you have a flywheel/flexplate with a center hole that matches the crank on the 400.
