Don Terrill’s Speed-Talk

I read a few threads on this on this forum and quite a few on other forums like yellowbullet and turbotech. I am trying to figure out if I should keep running this turbine housing or should I put on another? Another question is where is the ideal place to check the 2 pressures. I am comparing agains...

My understanding was the round coil because of the heatsink?

I have a Isky ground 212/212 561/561 on a 112 in a stock 5.3 with shaved heads. It can idle down to around 650 with pretty good chop, but I brought it to 725 and it still has a good idle. Extremely good low end and midrange. I had a dyno graph somewhere but it peaked around 5600 rpm.

Yep! Engine Dyno. Like I said I am a lot farther out than you are, haha. Goal is around july/august. Im hoping to get close to around 700hp around 7500rpm. That's just hopes and dreams right now.

For now I am running the GM one. I got it dirt cheap brand new so I will try that before going to a victor or something. Thinking about a 950 carb, or again if I can find a cheap dominator just to try. I already have a turbo 383 6.0, and then I started looking at all the parts in the garage, and was...

Yep, It is kind of a side project so nothing too serious.. yet. 6.0 bored to 4.070. Leaning on my stock ls3 heads ported by LandSpeed, reuse the ls3 valves. ls7 lifters, l92 oil pump. 3/8in pushrods. ls3 rocker trunnions. 14 to 1 e85. 3.9 K1 crank.

any updates? I was curious on this build. Its too much work, but I want to see results of the offset dowels vs straight. I am building a ls3 headed carb engine also. my cam is going to be around a 255 260 on a 110 lsa hyd roller.

I did just notice the prostock heads are towards a 10 degree cant instead of the stock 4-5 degrees. I guess I am totally curious now of the results, and then to find out the method of getting there. I guess I want to see a bbc head "shrunk down" on a sbc, like along the lines of a sdp or a...

doesn't the canted valves have some sort of play in this? Larger lift=less valve shroud?
