Floor and tunnel are done. Just finish off with the Tig and on to body filler to smooth all joints.
Shift boot conversion worked out great.
You got that right. Those trucks were NEVER considered for traditional hotrods
Floors are done with Tig work. All items sandblasted. All that is left is install hinge and door for Master Cylinder access then fill all weld joints with body filler.
Brake master cylinder access door is done.
Seat base is completed and ready for filler. Zips water pump housing has been debured and sand blasted for a clean look.
Doing something different with the exhaust... going to copy Foose's idea for his P-32 Roadster.
I notched the grill to make room for the frame rails because of the pinched front end. Also notched the firewall to make room for the dist cap and wires.
Imitation is the sincerest form of flattery...Saw a custom hood ornament and thought I would make one for my Rod.
To Be Continued...
The hood ornament is slowly being carved.
Made a panel that will hold the switches...
My Rolling Bones copy hood ornament is near completion. Need a coat of primer to finalize details...
Started filling the firewall...
Most of the filling is completed...
Black epoxy primer is applied to all bare metal surfaces. Next step high solids primer.
Got the RollingBones rad cap ornament painted & installed...
Dash holes cut for gauges...
Welded up a signal stock for the turn signal toggle.
Steering rod is cut to length. Fuel tank mounting is finished. Header pipe is tacked together in preparation for the side exit exhaust...
Got some high solids primer on...
Headers are slowly coming together. Hood & sides also showed up...
When I first got my hot rod on the road I was running a SBC, T5 w/.63 OD, 3.50 gear and 31 inch tires. I could only use the OD on the highway and even then at 65 mph I had to downshift to pass anyone. Why is this relevant?
The Tremec's OD ratio of .63 will not work well with your 3.23 final drive ratio. You probably won't be able to use the overdrive because your motor will be taching maybe 1,300-1,500 at highway speeds. Rear tire height can fix the issue, but I doubt you'll be running 25 or 26 inch tall rear tires. You may want to run the numbers on a 4.11 or 4.30 rear gear. With a lower gear the car will have a lot more grunt through ALL the gears. At what RPM did your 350 make 290 horsepower? Engines perform the best (both economy and performance) when they're operating in their designed power band.
Here's the formula to figure out the right combo:
MPH x Rear Gear Ratio x 336 / Tire Height x Overdrive = Cruise RPM
BTW, your fabrication is exceptionally clean – very nice work.
Dave's right about the gearing...(ask me how I know)
ATTN Mr GROOVY...…...don't break your arm,pattin yourself on your back
Got no idea what you mean...
Sorry, wasn't meant for you. I was responding to the post about patting yourself on the back.
I have no idea what he's talking about, as you're doing an outstanding job, and I look forward to watching the progress and your skill level. Carry on, brother, there's a lot of us out here rooting for you.
Slow progress on the headers. Clutch pivot point is marked for welding.

Great build. Enjoying the read.
Hope you don’t mind my 2 cents but maybe my experience can help.
I did a tko600 behind a zz383 in a 32 five window. Used a 3.50 rear gear set and rear tires were 700r18 tires. It had enough torque that rpm at 60/65 mph in fifth (o/d) was ok (just ok).
In the roadster, I used the same trans, same rear gear set and 750r16 tires (same dia as the 700r18s) behind a crate 350 with 290 hp and it sucked. Both off the lights and lugging in o/d on the highway. 1400 rpm at 60 mph wasn’t going to work with the lil 350. Ended up yanking the chunk and changing out the gears to a 3.89 set. And it’s way, way better. The extra rpm gets into the cams power band (for lack of a better term) and now o/d on the highway doesn’t lug and off the lights it’s a little more fun too.
The only other thing that you’re doing that I did, and then I changed, is the shifter location. I started by simply flipping the shifter in the rear location but ended up wanting a little more clearance from the bench seats in both the 5W and the roadster. Went to mid shift location and it works way better for me.
Again, these are just my experiences, and just food for thought.
With all the feedback about gear ratio selection I am a little worried...The trans / gear shop I bought my Tremec and center section said this combination would work. I told him I would like to use 3.23 for highway trips. I figured with the light weight of the vehicle the combo would be suited. What to do?
