I was wondering that maybe filling the outside corners inside the plenum areas would help airflow and throttle response. I have partially filled tunnelram plenums and achieved better "street manners", I.E. midrange and throttle response. I have done extensive mods to the chebbie 1982-1984 stock...

Depends on head flow, cubic inches and cam size... TIMINATOR

Me and my flowbench put the 440 ports bottleneck at the flange. Look at a 360/340, or small block chevy, the port opening at the flange is the same size! Look at the Speedmaster catalogue flow #s for the smallblock Ford, chebbie, mopar, and 440 heads, despite the 440s intake valve that is near a...

Thinking about running g a Max Wedge crossram on my new 512 build. Now my questions: What horsepower and torque differences would I expect over a big, modern, single plane intake with a 1250 or bigger Dominator carb. Are there any out there for sale and for how much? I have read that the earlier...

Keep in mind two things: "A crate engine is someone else's idea of what you want." Kinda like a mail order bride... Blueprint's "warrenty" requires you to remove the engine and send it back. You pay to R&R it, they pay freight. The last (but not only) Blueprint story I heard, a customers son...

468" and Pennzoil 40 wt. TIMINATOR

When I was a driver in a friends car. After making the finals in S/G and the oil pressure had dropped on every of the last 5 passes but was gonna make that last pass to get runnerup $$$$, I won it. We tore the pan off of it later and the oil pump was laying in the pan! No issues with the...

EXCUDAME You are correct. But that's not the only reason for the gains. TIMINATOR

I think that he may have not understood that that the performance tweaks I did were done first and only the rods and pistons were changed and even the weights were kept the same. TIMINATOR

I change one thing at a time and dyno it. I used the same block, crank, machining, with exactly the same composition, mods, oiling mods, oil pump, same exact deck height, rotating and reciprocating weights, crank weight, balancer, flexplate, clearances, timing set, cam degreeing, and bearings...

Much shorter skirt. Prolly 150 gms. lighter

Only one change at a time, and dyno it. That's the only way to test. The scientific method! I was just mentioning other things that I have tried. As far as engine masters goes, there are not any two identical engines in there enough to draw any conclusions from. Different clearances, oils, oil...

It has been said that peak cylinder pressure should occur at around 15° past TDC for optimum power. This number depends on rod/stroke ratio. The more efficient burn chamber and longer rod ratio both allow less timing. Less timing means less "negative work" against the piston on the compression...

Nothings free Solid rollers for me! Buy once Cry once! Works for me! And happy forever! No SJ oil No flat lobes Wide power band Lotsa HP! Been doin it that way for 50 years with no regrets. My way is not for everybody. It's America, make you're own choices! Try everything until you find your...

Comps lobe library has always had a .904 diameter lifter section and will special grind others.. Many of us racers limited to flat tappet cams have run ford or mopar lifter conversions for a lot of years. I haven't run anything but rollers in any of my street or race engines since the late 80s...
