Really only two questions right now.
1. Has anyone on here used WOt-tech's "Little Thumper"cam? Would it be as good in a turbo 3.4 hybrid as tunerpro claims(450hp at the crank)?
Here are the specs:
283/275 Duration
.546/.536" Lift
111 LSA

2. Where do you guys that build turbo headers get the collectors from? I have looked on WOT-tech.com but can't find anything.
Thank you

I have a Delta 260 from Delta cams, many of the guys here can vouch it is one of the best.

For the flanges look on British Car Conversions, here is the link: http://www.britishcarconversions.com...nges-ih-detail

For the collectors, look on Columbia River Mandrel Bends, I believe they are the cheapest around here. Also you could look into log headers as they are much less complicated and cheaper.

Ok. I was planning on talking to Delta once I get my refund check. The real reason I was looking at the cam size from WOT is because of the sound and because of what the dyno estimator said it would make over the Comp Cams 260-260, 272-284 cams that I used for comparison. I did see that it is way bigger than what anyone else was talking about running. is is what it sounds like:

Thank you for the info on the collectors and flanges. The log manifolds would be so much easier to build, but I am a welder in training and there is something about the tubualr headers that calls to me. Might just make a set of logs though because of the ease and speed of manufacturing.
Thank you

For the collectors I remember getting mine from summitracing.com iirc they were about 30 bucks a piece for mild steel 3-1 collectors. Which I got 2 1/2" out 1 1/2" primarys.

wot-tech cams are all roller cams arent they, if so u cant use that with the 3.4 block , not witout modding it for the lifter dogbones

broke91firebird

I hadn't thought of that. Thank you.

Thank you both for the links.

if ur doing the hybrid use the delta 272 not the 260

What dave said. That's the cam i basically use. And it is about perfect for the turbo set up. I remember when i swapped from the 260 to the 270 grind, I literly added 50Hp of fuel especially in the 4,500-6,000 rpm area. I also gained 4MPH trap speed at the same boost level and tune else then that added fuel. (thats saying alot when your trap speed goes from 115 to 119Mph from a cam swap and new springs) But at the same time I also ditched the stock springs for some comp cam beehive springs. I was going to use lsx springs but after more research I realized that they are a waste of money as well. And the bind height was not nearly enough for me to safely use. I used comp cams 26986 Valve Springs. The total safe lift was something like .550-.570 with the 1.7 installed height. I run a tick over .500 with the 270 cam with the stock 3x00 1.6 rockers. For all I know i was floating my valves as well so the cam might not of added all the extra flow and hp, could have been a little of the cam, and a little from the new springs.


If you are going turbo though, and based on your converter stall...exc. You don't want to get too outta hand for the duration and the LSA. It will drastically reduce your spool up. Call up delta and tell them what you have and go from there.

If you want I can dig up my cam card for you for the 270 I have.

Ok thank you. While on the subject, what stall do you guys run? I am planning on currently just running the stock 700r4 until it pops and then get a more performance orientated one built.

C2YT

I think I have a 2800 stall? It is what @FastEddi was using before he swapped to the TH350.

most of us have used the 105$ autozone high stall converter to start the more power u make the higher it stalls but at the same time that means its slipping more
a custom converter is worth it for how much more power will make it to the ground , but that cheap 105$ converter is a good start for about 85% of ppls needs

if ur going to keep the 700 spend the 300 or so and have freakshow build u a custom stall
i used to recomend tci converters but the 60* converter is no longer an off the shelf product. they will custom build one but its a couple hundred more then the freakshow

its a shame cause those tci converters were on the money its whats in my car , i had it restaled to 4,500 rpm and they nailed it , that thing has like no slip on the top end of the track

Yea I ran that 108 dollar converter for 3 whole years in my old 700r. I will say i mustof had a freak one because it took a pounding. Best I ever went with that thing was a 11.70@115Mph. That's literally 400-440hp in front of that poor thing..lol I have to say that the stock tq convterter suxs if you ever run a turbo. Terribly! Back when i first turboed mine and had a stocker in it, it was flashing to about 2k on my datalogs. Now if you don't have a tiny undersized turbo......well there is some major turbo lag as the turbos lower boost threshold is so far away from the flash rpm that it seem like forever to hit the rpm area to start spooling.

I will say it really had some massive converter slip though the faster i went. Something like 22-24% when I ran 11s with it. My new freakshow converter has about 6-7% of slip depending on trans temp exc. So I can now trap 120mph at a lower rpm then the old converter at 115mph and let alone alot more power is getting to the ground.

But for anyone wanting a better then stock stall and something that will handle 200-300hp easily then this thing will work quite well. Mine stalled at about 3k rpm when I left without the turbo spooling. If i spooled it up at the line it flashed to about 3500 rpm because of the increased tq at the line.

I called freakshow last year before I decided to go the TH350 swap route, they said it would be 370 bucks for a converter shipped to the house for the 2.8/3.1/3.4L Rwd. Thats not too bad at all. You can stall it what ever you want as well. Their converters are pretty damm stout. There th350 converters go for 320 bucks. Ive ran mine all year and its consistant and flashes the same everytime with little slip at the top end(for how much the converter cost). I would recommend them anyday for someone making less then 500Hp.

Yes you have that converter in the link that i just posted. It stalls at around 2800-3000 depending on your tq. With your build probably around 2800 rpm for the most part.
