I have a 355, AFR 210 heads,forged crank/rods/pistons. Hydro roller cam and Vic Jr with 750 Holley double pumper/NOS Cheater. I shift at 6800 rpm. Is the Super Victor a worthwhile investment? I am just trying to get into the 10's.What would I benefit from ?

 

Yes and no....

first what size is your cam?

then i'll let you know my opinion

 

the cam is an FTI custom hydro-roller cam,
308/316 advertised duration.
240/248 duration at 0.050"
575/595 lift.

I know I would greatly benefit from a built automatic, but I love the T-5 and it has actually been holding up, plus the car is about 70% street, 30% race....compression is 10.5:1,heads were also worked by FTI, they flow 299/231 @ 600 lift.... opinions?

 

Yes i think you'd benefit from a super victor

you have the head flow potential and you have the cam to shift appropiately

just realize that you are going to have shift the car much higher in the rpm band

i would be shooting for 7000-7500 on motor and 6500-7000 on the gas. You have a fairly large cam

 

thanks,and would I benefit a lot more from a TH350? with a brake?or should I just get my T-5 pro shifted?

 

an auto with a t-brake would definately be more consistent and easier to make go 10s....but since you are having some good luck with the T-5 might as well stay with it and try it since you like it so much

its not like people haven't gone 10s with sticks

Also, if you plan to modify a T-5 to handle a lot of horsepower i'd look up these guys. They do extensive modifications and are suppose to hold more torque than any other T-5 based tranny

thanks a lot, i really would hate to give up my T-5! I hate autos...

 

there is always the T56 swap, they go in place of the T-5's with the right parts so nicely. The only problem is the bell housing two of my car magazines just did an artical on T56 SFI bells, I dont remember which two mags it was. the bell was gold, McCleod maybe? The T56's take alot of abuse as long as they are the ones made in America by Borg Warner (LT1 T56's). They seem to standup well even on really modified LT1's ( nitrous-blower ). Whereas the LS1 versions being "hecco'd in Mehico" by Tremec don't seem to be cuttin the mustard even on unmodified cars.

 

nobody makes a SFI legal bellhousing for a T56

 

so is there a mag article or what? anyone know? does anyone make one or not?

 

make what? a sfi legal bellhousing? no, they dont.

The best you can do is use one of those SFI tranny blankets and those aren't totally legal either

 

the blankets are legal at our track, i just didnt think you could use one with a stick, thats all.....

 

I run a super victor on a much more mild motor than that and I dont think it is hurting me any.

 

you would be better off having your intake ported by a VERY competent head porter. you can go tens quite easily with the victor jr, especially if it has been opened up and massaged in the right places.

hell, if you dont want to bother, yeah, a super victor would work fine, if you have the hood clearance for it.

tranny blankets are legal at ALL tracks, but they are only legal to a certain ET which alludes me

i'm not sure if it is 10s or 9s

 

It was in two new magazines (maybe last month or the one before) I will scan and post when I find it.

 

 

whoopsy....

are you sure that this picture of the SFI bellhousing fits the F-BODY T56 and not the VIPER T56?

i know that the VIPER T56 has a SFI bellhousing but i've never heard of a F-BODY T56, if this truly fits the F-BODY T56 this has been a long time coming for the fast guys using a T56s

 

Actually what it is is a part of a set that is used to make LS1 trannys fit behind regular chevys. It comes with an optional spacer and adapter plate that are used in different combinations or not used to fit all different kinds of trannys behind chevys. With this set you can either adapt old style four speed or tremec 5 speeds onto LT1 cars or put a T56 in your chevelle. Its a set designed to fill the gap they consider it a versatile kit. I scanned the article pages but I don't know if I should be putting them here on thirdgen.

 

ok, i'm a little confused.

so this is SFI legal but will only be if you swap in a tranny other than a T56?

am i getting that right

 

no, its is SFI legal and will work with a variety of trannys including a T56.

 

this is big news for the T56 guys then....i'm ASSuming this is a new product then?

 

yeah the info came out three months ago , but the only problem is I have been calling them for at least 2 of those months and sending emails, no response and when I call I get either a ring ring ring or a busy signal. no further info on availability, pricing, or part #'s

 

i would be shooting for 7000-7500 on motor and 6500-7000 on the gas. You have a fairly large cam


From past experience you do not want to be shifting that at that rpm range with a hydraulic roller, rev kit or not. 6500 - 6800 is about all you really want to be at. We have a bigger cam than that "248-254 @50" in a 406. that car was shifted at many rpms before we found the best to be about 6700. we also have that same cam above in a 406 which is only shifted at 6500. and again in a 355 which is shifter right at 6500 as well. on the dyno with the cams above the showed signs of valve float above 6800 in all cases. just thought I would share some info here...

whoops, i must've missed the hydraulic part. I saw the duration/lift #s and just thought solid

 

no, i had a bigger solid roller before but i hate pulling *** damn valve covers every week to set the lash....that gets annoying, so i swapped to hydro-roller and a little more N2O,

 

and im sorry, I dont know what bad experioence youve had with a hyro-roller cam and where you get that it doesnt like reving high, but I could rev mine to 7200+ but I choose not to cause I dont think the block would take it, I mean, my first time out with 488 gears, I was almost reving to 7500 rpm in the 1/4.I got too much invested to blow it for a few 100 rpms.....

Also, your 406 is much bigger then my 355, and it is a very basic rule of thumb that the bigger engine doesnt have to rev as much as the small one with the same cam for it to be at the same power level. And I dont think you have the same cam, unless you have my exact combo, cause all of FTI's cams are custon made, to the motor and to the car//tranny.......

 

no it is not an fti it is a comp cam 240-248 with 570-590 lift, but that is not the case. same cam or not reving a hydraulic roller at the rpms you are saying is not a good thing period i dont care who makes the cam. but hey its your motor your cam, and I had the same cam in a 355 as well. just invest in a couple of sets of springs and you will be fine.

Drew

 

no offense but you either didn't have strong enough springs for the cam you were running, didn't have strong enough rockers, or wasn't running a stud girdle, or finally runnng shaft mounts

if you have strong springs and at a minimum a good strong rocker with a stud girdle you can go just about every oil change before checking lash again

 

I must admit, I did cheap out on the prings the first time, but the motor was a little too radical for the street with the solid roller cam. Well, I went and did it today, I ordered the Super Victor with a new Holley 4150HP(830cfm). If nothing else, Im sure my N/A times will get better. Stay tuned.
