Twin turbo Small block

Looking at building a twin turbo small block in the future, will be using a 48* R3 block but need to decide on what heads to run. I like my indy 360-1 cnc raised port heads and they are 6 bolt but Eddie keeps telling me to dump them.

So I was thinking of going W9 heads or the new Victor heads. I have a real good line on some 48* 6 bolt W9 heads with tall deck intake for a really good price. I was originally looking at the victor heads but I think they are 4 bolt only and think the 6 bolt head would hold the boost better.

Why wouldn't your Indy's work boosted?

The cylinder head doesn't mean much on a boosted motor. I made around 700hp with a .500" cam with only 250cfm of head.

How much are you looking to make? I'd guess a 360-1 would support 1500hp pretty easy.

They aren't known for the best reliability but I had a crack in number four once, since I had it fixed and sealed I haven't had any more issues with them.

looking for the 1500-2000 range, the cylinder heads matter over 1000hp trust me.

I dont know how much the W-9 would take pressure
wise.. they are a light head.. basically its a
cross between the W-7 and the W-8 and lightened
up to make a W-9.. if you could get a set of W-8s
they would be the BEST out there.. would the W-9
work.. sure
EDIT
what size turbos are you looking at to make 2000hp
and how much pressure.. I assume this will be a air
to water inner cooled

was thinking about the same as the P man.... W8 would be the go to head for boost.

Try picking up some W8's if you can. Otherwise the Victor's would be worth looking at

Last time I talked to Brett he told me I would have 5-7500k in a set of W8 heads

Weren't you thinking of a G3 build?
W9 are gonna take some machining to work. AMHIK

There was a Duster on Drag Week with a boosted Indy headed small block. It was going faster everyday, I think he ended the week in the 8.70s? B3 Engines or something like that was on the back window.

That duster has been 8.20's with indy heads and a single 98mm. At monster mopar it went 5.20's

The answer to "not enough CFM" is "more boost".

I've got a twin turbo R3 with the new Victor heads and I'm right here in Jacksonville, too. Your welcome to call, come over, or talk with my engine builder.

Sweet, when I get my truck running again I will have to cruise up there and check it out. Doing some upgrades I have been putting off and changing my oil pan

Big3. He was running an R3 block 400-something inch from what he told me, and he had to slow it way down because they wouldn't let him run faster than 8.50 with his cage, so he started out safe and tried to dial it in towards 8.50. He said its capable of 7's. I had a picture of the setup but can't find it

do a ebay search on w8 heads right now.. just a fyi

How much HP can an R3 block take?

More from a turbo than from NA or nitrous.

its not the flow of the indys they are prone to cracking and with boost it increases that even more so prevention is better than cure
