Don Terrill’s Speed-Talk

the current cost of hyd roller lifters is absurd, just not acceptable for a budget build, for a low use engine your current lifters should work fine with a street type solid roller lobe, maybe a cam expert can tell from the cam core you have if it is feasible to regrind or you might be able to sell it

duct tape worked perfectly well

left out a couple of words in my long explanation, "the same" .050 duration, example- a .600" lift on 230 deg @ .050 lobe is more intense than a .500" lift on 230 deg @ .050 lobe

you need to use packard 440 plug wires with rajah terminals to be period correct

download the Comp Cams lobe profile catalog and look at page 71, the "MI" on the left stands for major intensity which is the difference between advertised duration and .050 duration, a lower major intensity figure indicates faster opening and closing-typically called more aggressive lobe,...

look at Weingartner's youtube videos where he measured runner lengths and cross sections of intakes

I'm surprised solid core wires are still made, saw an episode of "Roadkill" where they blamed them for ignition failures, what is the intended use for them? generators? boats? hope not in aircraft

one of those links has the rod length at 5.75" and the stroke is 3.25" so the deck height might be a tad shorter than the SBC, I see the LS Chevy is said to be the same 28" long, don't know if that is bellhousing to front cover or what

probably no aftermarket chokeless main body for vacuum sec carbs, the air cleaner flange is 3.25" high-add 1/2" to 3/4" for vent tube

does anyone know the outer dimensions of these engines? deck height? block length? the bore space is 4.15" best I can research, considering a swap, the OHC heads must be pretty tall

the Allstar 26092 says it's inch and 7/8 drop, the Holley street demon carb measure 4.3" from intake flange to top of choke tower with the link protruding another half inch

you never answered about your climate, do you need a choke? do you need the exhaust heat? the ED 2161 and the Weiand 8123 claim to have carb height of 4.85" they are fully divided, even the price is similar, no real difference between them, the Speedmaster claims to be .200" lower and has ...

I would use the shorter manifold and fit the heat insulating shield spacer like came on Chevelles-don't know if Camaros used them, iron heads would concern me with modern gasoline, what climate are you in?

their description says the RPM has about 3/8" higher carb pad and won't fit 67-81 Camaro, do you have scoop or lump in the hood? my expeirence on a 1970 model with the 569 factory rectangle port manifold showed maybe a 1/2" hood clearance with the stock open element Chevy air cleaner which...

every person whoever floored the gas pedal from stopped in a vehicle with a stock torque converter ran the engine from about 2000 rpm at full throttle, bound to be 10's of millions of users, maybe over a 100 million
