I've always wanted a set of w2's. I'm getting into the sb game now also, so I guess I start looking.

Hey my logic is a ported W2 ought to flow on par with a fairly well ported Edelbrock big block head. So I got 440 cubes in a small block package (not to mention a super light bobweight) so it ought to be pretty darn fun!

It's the same logic I used with my 427 Cobra replica, instead of an FE 427 it has a stroker small block Windsor with heads that flow as good or better...same powerband but much much lighter.

What's the number?

Not sure yet but the plan is with the 4.25" crank having 2" sbc journals and using a 6.200 rod that's going to allow me to use a super light 1.26 CH SBC (for a 350 SBC with a 6" rod) Icon race piston and pin and we'll just flycut the valve reliefs for the Mopar valves

I figure the Bobweight should be sub 1800 grams or right at it, a good bit lighter than most 408-416's wind up with 1.47 ish CH.

My 408 was 1800.

Hey Wize , what happend to those heads you were testing a while back ?? I haven't been on here in a while. Did they ever work out on your rocky ??

Yes sub 1800 maybe closer to 1700 and 1800 is right around where most 408-416's wind-up (as is mine at 1804), but how much lighter I'm not sure yet but I know those Icon slugs are very light compared to the standard 4" mopar stroker slugs and the ch is ideal, so why not figure out a way to use them?

By super light I was really thinking more to next to a comparable 440 cube big block.

my 436'' with Molnar 4.125'' crank, callies 6.200 rods, diamond pistons is 1766 grams

Joe,

Still figuring out the hook....last time out with it I babied it out of the hole and with a crappy 1.81 60' it went 7.33 and 97.76 in the 1/8th. The power is there just got to get it to launch full throttle, running 11.30's when it should be in the 10.70's has been frustrating, I'll figure it out though.

79410, yeah that's why I'm thinking around 1700. the skirt design of tht SBC ICON race piston is very similar to the SRP, My Machinist Hollis page thinks we can make them work and the bob will come up really light. The BPE 4.25 crank also has the smaller 2" journals so the rod throws themselves will be just a tad lighter as well.

The new LS style pistons are sub 400 grams for a 4.00-4.06 bore.

2.08" intake 1.600" Valve is all that will fit. Small block mopar valve spacing is not good.

I have seen 2.100" intake and 1.600" in w2s with tight guides still had slight valve to Valve rub.

In a 358 sprint car engine I did I ran 2.100" 1.58" Valves.

Thanks!

I think a good 2.08 incher with an 11/32 stem would work great for what I'm planning. I've seen 2.12"s going in W2's back in the 80's but that may have been coupled with a 1.56" exhaust valve (and maybe a bit of fancy offset guide work) but I know it has been done before.

I know I'll be swapping out the Cam Motion 261/266 @.050 Mild Endurance ramp roller out of the 414 and into this one since it's a very streetable ramp, with the 1.6:1 rockers it will be .628/.604 lift, should be fun.

Oh and the Street Dommy intake DOES look identical internally to the Strip Dommy, I think I remember how to coax a few more ponies out of them. Not as much meat to work with as you have with a Vic but it will serve my purpose fine.

I got to admit that the angle milling to get the valves to 16 degrees and getting a quench pad in the same motion has got me thinking.

I gave $850.00 for the 2 bare heads, A full set of offset intake roller rockers, billet shaft blocks/hold downs and the intake, not too bad a deal I reckon.

Here's a pic

Never ran W2 heads...... but have a Holley Strip Dominator W2 intake in my "wall art" collection.

I think Holley made a "pro dominator" W2 Tunnel Ram, wonder how hard one of those would be to find?

i got me a set of w-2s back in 1989 they were on a 340 i bought on a stand iv had them to this day and still havent used them, they need guides and i never had a short block with enough piston to head clearance to use them, theyre nicely ported race versions i think 1976 date code, i gota a 572 b1 work in progress now but one day ill hope to put them on sumthn
