It was a good day and I hope they do it again. There was a lot of interesting cars there that you just don't see everyday where we live.

If there's only $300 separating you from a stroker kit the I too would just do that. I seem to have my best luck getting a hold of Nancy in the second half of the week around mid day. Or sometimes beginning of the week in the morning the other guy that builds engines with Barry answers in the morning when he's not doing anything before anyone else comes in. Either way it's a pain but it will be worth it. I'm pretty sure the questions you have besides the cam are something we could almost answer here. Who knows maybe even pick the cam. Heck I don't even know of my cam was the best choice but we'll see. Idi were you I'd just order online and get the process started.

 

Ok, so here is the starting point -

• My block will be bored to 4.07, the deck will be machined to 10.175 (I know this is taller than the stock specification, but the block measured 10.177 at its lowest point and it had some surface rust so 10.175 is the expected height)
• Based on the deck, bore, stroke at 4.25, 6.7 rods, and the combustion chamber at 76cc (the volume on his site), what piston would make a 10.5 CR?
• I'm assuming the standard height for the piston would be 1.33, but I took that from the Diamond site. Survival doesn't provide any piston specs.
• Is there a reason I shouldn't go with the limited travel hydraulic roller lifters (the price is $40 more than the normal travel lifters)?
• What is the practical RPM limit on a 4.25 stroke (notwithstanding limits on cam, lifters, and valve train)? Eagle has an article that suggests that piston speed of 140 feet per minute is the limit, and one of the on line calculators suggests a 70 feet per minutes speed for a 4.25 stroke at 6,000 rpm. Seems a non issue, but I'm curious.
• Given that we are going with Felony heads, the stroker kit, and a new rocker assembly, what is the strongest cam for that setup.

I know the standard answer is "it depends on what you want to do". I want to accelerate. The truck is a street rod. It doesn't spend time in traffic, but it isn't a show truck. When I drive it, I'm doing it for fun.

I'll be looking for some guidance from the vendor, assuming they have built more than a few of these.

 

Well that sure quieted things down!

 

Sorry I kinda forgot about answering anything in here. That other thread had me concerned about my rings. I got a answer on that today from Barry so I will continue on. I'll have to read your questions this even when I get back from the hospital.

 

Didn't see a thread about rings. Hospital and concerns about rings. Two things I don't want to think about.

 

I kinda answered some of your questions in my build thread . .

I think max power around 6000-6200 would be plenty high to spin it.

But being your truck is a bit heavier keeping the power band a bit lower to say 5500 rpm peak hp where it would buzz to 6000 no problem would be my opinion.

I would go with a hydraulic roller cam if $$ avail

Barry has done enough to know which one would work best for your combo.

What octane fuel do you have up there?

I answered more in my thread as did not know what the OP would think here.

 

Boss9F100,

I am going with a hydraulic roller cam and I think roller rockers as well (I see you used OEM rockers on yours and was thinking about staying with them). I was thinking about peaking mid to high 5,000s and, as you say, spinning to 6,000. Before I yanked it the 410 was flat dead at 5,000, my rear wheel dyno results have been posted a few times, healthy torque but no HP.

We have 91 at pretty much all stations, some carry 93.

 

Yea the rings I could deal with but my Dad is still very sick and fighting something unknown.

 

Sorry about your dad. We had mine measured for a pine box when he was 90. We wouldn't have given a dollar for his chances to see his 91st (December 28). Started getting sick in September, watched him fade in front of our eyes. Just before Christmas he started feeling a little better, joined us for the big feast, and at 95 he is over in Victoria for a little holiday with our mother.

Best of luck to him and your family.

 

Thanks. It would be a little easier if he wasn't 58. He keeps getting perforations in his small intestine and nobody around here knows why.

 

I think to get the compression you want you will have to go with flat top Pistons. He advertised them as 11:1 but you will probably end up with a little less.

 

Took the plunge. Ordered a Prison Break kit with flat tops. Going for a 10.5 to 1 CR. Also ordered FElony heads, and a 234/240 hydraulic roller cam and lifters, and an 830 Quick Fuel carb.

Should be fun.

 

Nice.

I don't think you'll be disappointed.

 

That's awesome! Now in 6 months when you get your parts you can start building too! I shouldn't say that I hope you get your stuff a little sooner.

Barry recommended the Quickfuel 780 for mine. He said it's more bang for the buck basically over the Holley. I haven't gotten much of a chance to look at them yet.

 

Did you buy the limited travel lifters? I just got the normal ones he sells.
