I have heard up to 40 hp on the dyno as a result of swapping carb spacers.Is the wilson tappered 4 hole spacer really worth 200 bucks ?

Any recomendations for a 540 with a 1050 dominator ?

I installed a 1" taper spacer by Wilson and picked up some hidden rpm. I didn't pay 200 hundred bucks but the results I got were worth it. It did produce a leaner condition but I was running rich before the install. I hopethis helps.

HVH makes a super sucker for around $100.They work as good as any.40 HP is a pipe dream.10 to15 HP is more reallistic.

I agree with JC on this one. Petelle's 1" spacer is worth 10 to 18HP usually but a jet change is needed because it will lean the engine out.

I think 40 hp is a real pipe dream but if you want i have one i will sell you for 150!!!!
and i will install it for you.lol

40hp doubtfull, more like 10 at most. Its more like one of those every little bit helps mods.

Wilsons spacers are 180 bucks a pop !!!

I know HVH's works, NASCAR outlawed it 20+ years ago from Cup.
