Of 331-347 cubic inch strokers.

My thoughts are that there are too many of these fully built combo's that fall really short of the type of bar the LS1 has put up.

Built right, these cars could put down similar numbers in similar RPM ranges.

I remember when the bar for LS1 was 400rwhp, then 420, then 440 and now it appears to be in the 450-470rwhp range for hydraulic cammed, street cars that don't need to rev to 7000 rpm to make their power. The rwtq is phenominal too, looks like the really good combos are in the 400-430rwtq range. This is a true testiment to the EFFICIENCY of these combos.

Most of these ford 331-347's are putting down around 350-370rwhp and 350-370rwtq. This is a far cry from the current LS1 development.

On that side they are saying you guys spend ALOT of money to get the type of power.

My thoughts are is it costs in the $4000-$7000 range.

Heck some of the shops such as LG or MTI should put out ford packages for the ford guys so they can get a taste of real N/A power.

Only NA Ford stuff I follow is the big cube Windsor stuff.

It is not uncommon for a 347 to go over 400 RWHP, not so bad for engines that have not had a whole bunch of development work in a decade.

I feel same as Pro Stock John, Windsor is more interesting and better choice for builds. I will say from playing with TFS 5.0 heads that they have come a long way with SBF head flow and this makes great potential for making power. Anything can make good power with nice heads, now you need to fit longer rods in block and reduce main bearing diameters......

The LS1 stuff will just continue to get better and better. Ford only seems to have any chance on the street with power adders.

you must have over looked fords release of the mach-1 which is only 281 c.i. n/a and is running stock ls-1 times and mph <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Beacause ford came up with an idea of putting an overhead valve in the mustang when at the same time gm quits production of the f-body all together has to tell you some thing.And gm didint put 32 valves in their cars we can play the what if game all day long.And yes the f-bodys are making more power than the mach,s but you need to do alittle more reserch cause they are running identicle mphs mind you with 70 less cubic inches.

GM continues to prove more power and reliability comes with basic designs than crappy ohc no flow designs even with 4 valves im not impressed!

106-109 traps are impressive. However, there are factory freaks out there which include ls1s that have run 111-112 traps stock.

Take your prozac,FACT I've seen more ls-1's with rods hanging out the side of blocks that any ford motor,FACT Where not talking about caddy motors were talking about motors put in mustangs and f-bodys,FACT You dont know when I was born,FACT The 03 cobra motors dont put down reliable power?They've used the same basic desighn in the lightnings for over 5 years RELIABLY,FACT and I have worked on several dohc&ohc mustangs and they are easier than most would think and are way easier than GM,s lt-1 I have also done motor swaps on DOHC cobras,FACT Seriously dude you need to relax,FACT with that being said I've said my piece and I'm out,FACT <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
