11r 190 or 185 renegade 347 street /strip

[Hmontgomery88]

I’m in the process of building a347 with r11 190 or 185 renegade with 35/775-8 can witch head and why

I’ve got a 88 mustang gt daddy brought it brand new. Rt now it has a 306 with gt 40 heads and 3.55 with a tremec trans then basic stock

Either one will do.
If it was going to be a build that could come close to taxing the abilities of either head, then you could worry about which one was "better".

For me it would depend on the piston used and goals of the build, since its all ready got a .030 over if its cut for a decent inline relief you could probably get away with more cam on the inline heads. Though the 11r can still be pretty aggressive without any fly cuts and are offered in a smaller chamber. If I had a 86 junk motor and a budget for either of those 11r would be my pic. There also decent as cast China clone options for the afr heads these days you can build out for half the price and be extremely close in flow and the quality of valvetrain. The fact afr its self is using Chinese core castings now in the renegade line and kept the price point the same is another reason I would pick tfs over those if buying new.

Might want to look on eBay there doing discount codes again where you can knock 15% off up to $100 off two seperate orders, pretty sure it applies to summit and there listings for TFS heads

You can never have too much head.

 

[Hmontgomery88]

11r 190 or 205 heads

 

[Noobz347]

11r 190 or 205 heads

If you're not worried about smog provisions, I'd choose the inline AFR 205 or 225s.

cc of port volume means little when comparing an 11r vs an inline head but a stroker, 205 version...
