Don Terrill’s Speed-Talk

New name,same game will be played.It will all take no time to happen. I don't think so fabr, this was a line in the sand moment for Summit & Jegs. Summit said they will destroy ALL Speedmaster parts in stock and not return any parts back to Speedmaster. Speedmaster will only continue on Ebay an...

Well done Summit racing!!!.....Now Jegs has also dumped Speedmaster parts from their site.

About time the little guy had a win congrats Broader performance.

You would gain with 850s but not for money spent. You would Def be happy with a pair of doms and see better improvement. I went through same thing with 900 plus hp sbc. Braswell told me when I went from 865 hp to the 935 setup that his 850s would still do the job. I ran it 3 times, about 7 passes. ...

Slide rule says 9.95 @ 134 mph @ 3500 pds and 650 hp Steve I ran 6.17 @ 108.8 @ 2050 DA, 5 MPH head cross wind @ 3470, I will get into the details tonight. Impressive nice job. What's interesting is Chooper Scott on here with his camaro ran that exact time in the 1/8 then ran 9.81 @134 but he is 40...

As an Aussie i am ashamed of what this company doe's to small business owners and keeps doing. By now people should know what this company doe's........so stupid is what stupid doe's........if you buy speedmaster it's on you. Support small business like broader, because like he said he put's his hea...

As for the Moroso calculator. One example I have is as follows: 86 IROC: 3650 lbs., McCreary Road star tires @ 26", 3.27 gear Engine 2007 353: 4.020” x 3.48” 670 Holley RPM Air Gap Vortec heads. Comp XR276HR (in 2 106 ICL) 10.05:1 Cranking pressure 185-190 May 11 2009 Chassis dyno Max power: 2...

Weighs 3350lb on the scales on the ring rd BP.

If you go to Calder you'll have to drop in and put it on the individual wheel scales.

Scaled this beast recently.

My guess Tom 4750lb.......

If you want longevity, just put an ls and make it look like a stock factory looking 350.

APD Carbs are starting to make some nice rockers, only BBC at the moment, but will expand over time.

Which ever one you choose, put a steel rocker on the exhaust side..........you will thank me later.

I don’t think any more power will be squeezed out of this small head 401 sbc. So time for a bit of fun and revisit the guesstimates. I’m calling it 568hp @ 6500rpm and 532ft/4900rpm from a run with 975cfm carb that wasn’t influenced by multiple runs (the 571hp/538ft/lb run) Ok as a Ford man i'll go...

I'm trying to do everything i can to get my new race car down to the weight of my old car that i crashed. So when i show up at the track in theory it should run at least the same speed. This new car has a few things that add weight and a few things that are lighter but it ended up being about 53 po...

But if you have a engine designed for vac pump ,imo quite a bit can be learned. We just recently dyno tested a 380 inch sbc. We tried a new vac electric , new 4 vane from company we never tried before. Base engine made 893 hp after broke in. With electric pump that only pulled 11" it made 916 ...

Excuses as to why "Rippers" down 5 MPH to a heavier car with production heads. Gas & Carburetors NA

It's simple Ripper's engine is not making the hp that the dyno printed out.
