Yes I have the Super Victor #2891. In fact I bought it from Andy a few years ago. You fellas have made my day. I was thinking that to change heads was a money pit that my better half would squawk about. If I can use my bolt on parts I have then I will have new heads on the way shortly.
If I decide to port the manifold, how far up will I need to go in the runner?

About the only reason to use B1BS heads these days is if you work for the Koffels or Brodix. Other than that I can't think of a single reason why anyone would spend twice the money for something that requires custom headers and special rockers and doesn't make any more power. Koffel and Brodix should just admit it was an evolutionary dead end and move on to better things.

I see the same thing going on in the FE world. Over time, guys have created expensive FE heads that work okay, but now the new Trick Flow head is much less expensive and just as good or better.

My heads didn't get close to that number. OOTB. Mine were in the 270 range, ootb.

They are respectable after DP worked them. But no way Id buy another set, ever.

They had their place...many moons ago.

My good friend has been running 8.60’s-8.80’s for years in his charger so B1BS heads in the right hands work pretty good

I think the OP should consider a different cam to go with the new heads, etc.

What cam would you recommend?
Right now I am thinking that I need to concentrate on the heads then do more upgrades at a later date. I was thinking about some 1.6 or even 1.7 rockers with the cam that I have?

Digger73 (Mike)

That cam is way bigger than I have ran in any of my own bracket motors that are above 500 C.I. with both 440 size and all out CNC ported 440-1 heads I'm thinking maybe 260 to 275 @.050 ground on a 108 to maybe 111 LSA installed on the intake lobes 3 to 6 degrees advanced with as much lobe lift that you can get and use either 1.5 or 1.6 ratio rockers

I agree that 280*/283* @ .050 is rather large for your 11.5 comp.

With a mechanical roller, something between 265/270 on the intake with .650 lift should be a better fit. IMO I wouldn't even Try to use that big cam you have, don't bother IMO.

EZ choice to make

Andy ,
You say you used an offset rocker . Trickflow on Summit show Harland Sharp S70015KE , which lists for a Edelbrock rpm on HS site
Victors are listed as using S70015EVK which are .650 offset
So do the 270s use non offset or offset ?

Tex

Not offset. S700115KE supposedly corrects geometry issues with the Trick Flos. Just bought a set.

I said "standard offset".

Mikey's 470 that Pettis built w.11.7? comp has a monster(to some)cam and I think is even bigger than this one and he's flying w/an 1150 dommy I did and has a string of 6.0's and 9.50's...........My turd has 276-281 @ .050 and is an easy docile car to drive street/strip...........

I was quoting the flow advertised from Brodix. I was a bit curious about the 295 cfm rating too, but maybe they made a few changes in the last 25+ years from when I bought my set. I think the heads I bought were from the second batch of castings, and were not drilled in the front for accessories. I bought them from Koffels with stage I porting (kind of like port and bowl clean-up work), 1.6:1 ratio rocker arms, and cut to length pushrods and I think the bill was right about $3,000 (around 2001?) A few years ago I had them tested on the flow bench, and I think they flowed about 298 cfm?

Andy ,
I misunderstood .
"What rocker arms do you have now? The 270 uses standard rocker arms so what you have might work."
OP has Crane rockers for standard port Stealth heads .
Thanks for your input

Tex

Thanks markz528
So you could possibly use the Crane standard rocker if geometry works ?
I know it sounds like I am beating this to death BUT if I go this way I am looking at over $1300 of my quality Aussie dollars plus shipping .

Tex

Just to keep things off topic.......

I haven't had a B1BS in the shop in quite a long time.
As I recall, ootb they did flow close to 290...... But didn't get near that until .700 lift.

One thing I remember about the first one I tested was, the low/mid-lift flow was so bad I stopped about 1/2 way through the test to make sure there wasn't a problem with the bench.
I couldn't believe that an aftermarket head with a 2.20 intake valve could be that bad.

I ended up getting them to work pretty well...... Around 320@.700 while keeping the runner fairly small, and making some nice improvements in the low/mid flow.

On a flat top 446 in a 3900lb car they were good enough to let the car run high 10.40's with a single 850, and high 10.20's@130 with the MP TR and 2 x 750's on it.

You can use them if you can tolerate the geometry. The Harlan Sharp are expensive - around $950 standard price!

“ in theory” the HS “E” rockers are basically the same length as the Crane golds.

Yes or use the Mancini rocker arms. The Mancini rocker arms are a copy of the old Crane rocker arms. They are made by Harland for Mancini as a low end rocker arm. They work on the Trick Flow heads but are unbushed and probably won't last a super long time. But some race cars only make a few passes a year so in a situation like that they could last a life time.
