|igotachevyor2||you want be disapointed. the best i have done was a helical air raid spacer on a 4.0 jeep with a k&n cold air kit . it was a huge difference in the seat. i have ran several on sbc i think the single hole made the best improvement. also the wood is the better heat insulator.|

|6426yy||I tried a 4 hole moroso spacer on my truck because I have a single plane street master intake. The throttle response and off idle torque improved greatly. I eventually plan on installing a performer intake though.|

Who knows, maybe a spacer will improve performance. It doesn't cost that much to try one or even a couple of different ones.
Personally though, I would not be swayed by magazine articles that show power increases at the top range of rpm's, unless that's where the motor is going to spend most of its time. I suspect you can make more "area under curve" horsepower on the way up to max and the car would be faster without one. You can't race a dyno. Just my opinion.

|tornado-tech||HVH who makes the Super Sucker knows exactly which of their spacers will work the best. You have to up your carb jet size as you will lean it out due to more air flow. I had to rejet 3-4 sizes on mine but now can keep up with big blocks with my 362 as long as they keep stock valve angles on theirs.|

[QUOTE=400smb_s10]Well I would have to say 10 hp is 10 hp and it will bring me closer to the allmighty 200 hp from a stock 350 lol
This is on a 475 hp 406. Actually I gained 10 hp with the tapered style 4 hole spacer over a standard 4 hole spacer. If memory serves me correct I made somthing like 20 hp over no spacer. You wont see that much gain on a 200 hp 350 though.

Thanks again for all the replys and information on the spacers its much appreciated

|Steve karch||My 406 made 10 hp and 10 lbft more with a Super Sucker tapered style 4 hole on a Vic Jr intake on the dyno. Defintely works and I'd recommend it.|

They work, in addition to isolating them from engine heat they also help speed up the air/fuel mixture a little.

car craft has a write up on them in the september 07 book had some real good results one added like 20 some hp

|75sprintguy||a 4 hole phenolic spacer worked well for my set up my holley was bogging off the line so i put on the 1 inch spacer i felt instant throttle response i didnt have before and no more bog id say dont knock it till you try it|

Best thing about em is they cost less than the billet aluminum, and probably do more for slowing/stopping heat transfer as already mentioned.
