Re: Engine Machining Update

What do you think the cost to rebuild will be?
just curious, if I ever decide to do mine

Re: Engine Machining Update

Hondo,

I'd be breaking my TR6 Cardinal Rule #1 of never adding receipts if I told you. I promise that when, it's done that I'll let you know.

Searcher,

The cam is the new TH5 from BPNW, with their lifters made for the cam and dual valve springs. I bought the Vernier adjustable gear, so we'll look for the optimum torque curve when the cam is timed.

Compression will be at 9.5 to 1. Obviously I'm going to use the .120" shorter push rods.

Ignition base timing will be at 12BTDC and I'll tweak it in from there. I have three worked over dizzys to play with after it's broken in, which is when I'll really do the tuning adjustments.
 
Re: Engine Machining Update

Hi Paul, any plans on having the engine checked out when it's done to find out how much HP it will be putting out?
 
Re: Engine Machining Update

#6,

Yes, I hope to have it broken in in time for the annual Boston Area MG Club Dyno Day again this year. My wife and I are planning a several hundred mile run with the Cape Cod Club in early May to many of the lighthouses between Boston and Provincetown, so that will help rack up some break in miles.
 
Re: Engine Machining Update

I think that may be the same as a Kent TH5, Prestige says with the Kent TH5, Lucas PI, large valve head with some P&P, TR5 dizzy, and 9.5, I think he said 160 something HP at the crank. I drove a stock engine 72 today, good running, my car will blow the doors off it. I needed to see what a stock engine would do.
 
Re: Engine Machining Update

Searcher,

That is the same cam, you are correct. I have a dizzy with the curve that you speak of, headers, light P&P, but tri-carbs, not PI. Hopefully with all of that and the lighter flywheel, I'll get near 150 at the crank.
 
Re: Engine Machining Update

Paul:
Your photos look very familiar, reminding me of my machine shop days. Our engine programs are very simular right down to the ARP rod bolts. One thing I regret is I did not have the cam bearings installed. Good for you. The thing I recommend to all going this route is to make sure that the machine shop records everything, weights, measurments, photos of each step of the machine work and present it to you in a three ring binder. Then you know what you have. I will be watching your site for updates of this engine build and its performance output. Keep us posted.
 
Re: Engine Machining Update

Al,

I will have a digital photo record as well as written dimensions, weights, etc. Racing machine shops tend to do that more as a routine than a lot of the commercial operations.
