I am looking at trying a different intake. I am currently running a victor jr on a 383 stroker with 195 AFR eliminator heads my engine builder told me if i went to a super victor it would add a few horsepower. Has anyone tried worlds motown Intake Manifold from what i have read it might be better than the victor. Any opinions?

I run the 4500 series and am happy with the out of the box performance. It looks like a Dart comparing it.

Principle difference is a larger plenum volume, that is raised more, with slightly larger runners that will slow down your current air speed for less power. Unless you are currently running out of carb on the top end (and have tried the spacer option and discovered it does add power), the larger raised plenum will just give you hood clearance problems with no other benefit that I can see.

Which spacer is better the open or the one with 4 holes?

Your car will answer that question. Spacers are used to tune the intake. Generally 4 holes build torque and midrange power while a big hole contributes to plenum volume for the top end charge.

Big Dave, Beat me to it. The thing I'd add is, Is it a drag only? Or do you drive it on the streets too. A little more top end some times hurts the mid range.

i was gonna suggest the hurricane manifold before the read
i dont think its a repop of the super victor though
you can see that on the carb flange
super victor is parallel to the manifold bottom=race application
pp huricane is canted=street where the engines have a setback

i have the hurricane on my 355 just port matched and the 355 still wanted a 1 inch spacer

i chose this one for no2 duty vs a dual plane

I'm gonna try a spacer before I try an intake swap. The car is driven on the street just as much as at the track. So what do you think a 1" four hole spacer or do I need thicker?

Rolling Eyes ............... Laughing . you just cant resist can ya ? Laughing


ada1grant, youre going to have to try different spacers to see what works best. start with the 4-hole. i even doubled the spacers (made a 2") once but the Olds didnt like that at all Embarassed .

The open spacer will allow the turn better than the 4 hole and also give you more total plenum area.

To keep af2 happy I will say "Open first", but ...

You will not know which is better until you have tried both on the same day at the same race track; and then only if the car is consistent. Once you can make a back to back pass with the same time every time then you change one thing and test to see if it helped or hurt. Change back and the time should be the same as before for the next trial.

That is how you will "know" what works and what doesn't. You can further refine the intake with the use of "Turtles".
