Sprite 1275 parts list. 1.5 rockers worth it?

Sprite 1275 parts list. 1.5 rockers worth it?

Hey y'all,

I found great help here on my exhaust question and hopefully can get help finalizing my engine rebuild parts list.

This is my list from minispares, which isn't a finalized list of all parts. I still need oils/lube, clutch kit, thermostat studs and elbow, manifold studs, new nuts/bolts/washers, and radiator/fan/hoses.

I will go over my list with the machine shop that will be doing the work, but wanted you hear y'all's insights.

I am pretty sure I want to stick with the 10:1 pistons and 276 cam.

Are the 1.5 rockers worth it? I dont plan on any head work. Is clearance an.issuenwith 1.5 rockers and HC pistons? Will the below valve cover work if I use a silicone gasket?

I think I have been talked out of a lightweight flywheel. I had both the ultralight steel and the aluminum one in my basket multiple times, but not sure if it is worth it.

Thoughts?

Muffler for 1275 A series

Hey y'all,

I am currently rebuilding my 1275 for my Sprite. I am going to be upgrading to 9.75:1 pistons and a 276* cam.

My old Monza muffler is too loud and high pitched, annoying at highway speeds.

I do have an aftermarket header and only looking for a muffler. Any recommendations for something the would muffle the note a bit and bring it down to a comfortable range, while still sounding good?

Mk2 Sprite/Mk1 Midget Dash diagram

Hey y'all,

Looking at modeling a custom dash to 3D print or have cnc cut for my '61 Mk2 Sprite. Basically, I plan on adjusting the location of the gauges and making the dash a bit thinner to dree up some leg room on the driver side.

Does anyone know if there are diagrams of the dash panel that include measurements, radius of the bends, location of mounting points, etc. I don't plan on pulling my dash until the winter when I rewire the car and would like to have a new dash modeled and built before then.

How to train sled with TankMX

I only have access to a TankMX sled at my gym. I have seen the countless posts talking about how it isn't a good sled to train on due to the way it increases load with speed, but it is what I have.

Has anyone loaded it with weights and have an idea of they would recommend training with? On sports, I have only pulled sleds on grass, so I don't even have an idea what the Hyrox sled should feel like.
