Don Terrill’s Speed-Talk

I have a 355 with a decent hydraulic roller, 3500 converter and 3.89 rear gear.. I run the Edelbrock Performer mechanical pump with stock fuel line from the tank and 6AN fittings, line and filter to the carb. Turns 6500 and never misses a beat. I wanted a mechanical for simplicity

Has many used the Mowtown block vs the little M for their 434 build? Curious how machining varies between the 2.

Those also have an Ulta XD price tag. I know this stuff doesn't come cheap . Anyone know if an Oliver rod would have the required cam clearance? They are a Tad less expensive.

If I went to the 3.875 crankshaft would the run of the mill H Beam rod most likely work?

Those Scat I beams must be tough as nails.

I have not purchased anything as of yet. This build would be starting from scratch on everything. Engine will be street driven 98% of the time.

I am assuming building a 421 would be more clearance friendly

Probably because I don't have endless pockets$$. I know alot of people have done 5hem with an SHP block, just wondering what they used.

434 SBC Clearance Issues. Looking to build a 434 SBC with Hydraulic Roller for the street, in doing reading on the internet the rod to cam Clearance is a real pain with certain rod manufacturers. Does anyone have any real world experience on what rods that they used? Dart SHP bloc Callies Compstar C...

This was mostly a generic question. Horsepower goal would be 575ish at 6000 to 6400 rpm.

I currently have a 355, ported sportsman 2 heads, rpm air gap, 10.3 compression with a
.520 / .540 236 / .242 hydraulic roller. Runs strong and can drive anywhere.

What I am asking is it better to have a 10.5 compression engine with 64cc cylinder head or a 10.5 compression engine with a 72cc cylinder head.

With compression being the same. This will be a pump gas normally aspirated street engine. Hydraulic roller. 3500 converter, 3.89 gear. #3500 car

I have no particular cylinder head in mind. Can it be just a 64 vs 72 cc comparison or does everything else have to factor in?

Questions on 64 vs 72 cc cylinder heads volume. When building a Brand New engine and ordering parts is their a difference in detonation resistance, quench, hp, torque between the 2??? Researching 406 vs 421 vs 434. 10.5 to 11.0 compression for hydraulic roller street engine. Thanks

The converter is a Non Lockup. The car drives great in its current combination.
