Don Terrill’s Speed-Talk

Welcome to sloth talk, Home of the 5/64 ring iron headed 1957 tech. Here we will beat to death 1.94 or 2.02 valves. Highly discuss my 2" flow master ex, is it too much ? Oh hell yes! Where the whole board reads articles all day and hashes out what they haven't tried but are some how deemed exp...

SUMMIT did exactly that; they won't deal any Speedmaster parts anymore.

Speedmaster is a POS company. Summit Is verging on it as well, selling this shit. https://www.youtube.com/watch?v=9dsHrSq8pso There will always be people who COPY someone else's successful part but, to actually put the originator's name on it and try to pass it off as the real thing, is just "...

I have a 440 Holmes wrecker body mounted on a 74 Chevrolet C30 chassis. Current setup is a Carolina Machine Engine High Torque 350 longblock, (whatever that consists of) with an Edelbrock Performer intake, 1406 Carb, HEI distributor and small headers. Sling wrecker is PTO driven off a SM465 transmi...

Walter , thank you for the clarification on the rod side clearance , can you give me an idea on the vertical clearance and what rod journal size would you recommend for a 706ci engine NA for starters. thanks again. I can't recommend anything like that 'cause I don't build them ... I have witnessed ...

All I can say is that the Brodix 10 was a good head ... about the porting, I have no idea.

Why do you recommend .040 side clearance , that seems excessive to me , I would not want to exceed .025 to keep the rods from dancing from side to side , what would you suggest for vertical clearance , with what weight oil , also try the right side tomorro , your a little grumpy. Have a great day :...

nominal is 2.200 When running at about 7,000 RPM, a good steel 4340 crankshaft having a 5.300" stroke with that rod journal diameter will get about .035" shorter from end to end simply because of flex; be certain that the involved rods will have no angularity when running. Then the rod be...

Actually, with that probable 5.300" stroke, I would run minimum .040" rod side clearance and guide the rods side movement within the piston; (piston guided rods); similar to a 2-stroke. What diameter is the rod journal on that crank ? nominal is 2.200 When running at about 7,000 RPM, a go...

SBC, 406ci, 13:1 on E85, Dirt track engine, 1200 laps. Shaeffers 5-50 oil every 10 nights. Anyone here smarter than me? After the oil change interval results cam back every was really good except for a note of "high insoluables". I assumed race track dirt, It kept me up at night so I remo...

I got roped into building this using a myriad of parts. It is the biggest CI I have messed with and I am having some doubts about clearances. The patient: 706 bbc, 14.6, BME alum. rods, Pontiac heads, 300 shot of n2o, Dan Olson wet sump, vacuum pump, 2400 lb car, bruno trans. The rod bearing cleara...

After the "extended " additions are tig welded, I take an acetylene torch and blacken the entire area ... then ad oxy and heat that entire area until the soot disappears to anneal it, then cover it with cardboard so it cools slowly.

I have seen Larry Meaux weld up to an inch onto an intake runner divider. Is there any reason not to use 1/4 aluminum plate and weld that to the dividers instead? Then port and shape it accordingly? Thanks To extend a divider into the plenum area, I use 3/16" or 1/4" aluminum all the time...
