Camshaft/Bore Kit combinations

[satanspetferret]

I was on C&Ds site looking at bore kits for a 300ex. The site recommended that I install a high-comp piston with a cam. Does it apply the other way around too? If I just kit the 11:1 kit, do I need to order a cam as well, or can I wait until I have the money?

You could wait. It is just that they kind of go hand in hand. Somewhat like installing a filter with an exhaust. You could do one at a time, but it would benefit more from both.

Also take into consideration the labor you will save. It will be cheaper to just drop in a new cam while they have the rest of the top end apart. There is a bit more labor involved in tearing it back down to the point to drop the cam in after the fact.

Also, they warned that a 300ex starter may not be able to turn the motor with an 11:1 piston. Is that really going to be a problem? If so, what do I need to replace it with to ensure it isn't a problem.

[satanspetferret]

Oh, no, I'm doing it all myself. So labor isn't an issue. I am assuming that a 300ex is slightly easier to operate on than a 454 Chevy (out of a UL Hydroplane...).

the 300 will turn over a 11 to 1 piston no problem,i just installed one in mine.i am happy with just the piston and a exhaust system and i rejetted the carb.i dont want a cam right now because i'll lose the low end torque,thats what makes the 300ex what it is,itsnot much of a rever stock

Just save your money and do a 330 kit. Mine revs high, fast, and has tons of low end, mid range, and top end. I was extremely happy with the results. It gives my starter a hard time, but it turns it over, so i don't worry about it. Plus they are reliable.

Next question:

Do these 330 kits change bore and stroke? Do they actually increase your displacement to 330cc or something close?

[hondardr4life]

They just change the bore, not the stroke. And It actually does bump you cc's up to 330.

I don't think having a 454 in an airplane would allow it to qualify as an Ultralight;) :D .

Got any pics of it? (My dad is a huge airplane fanatic and I'm sure he'd love to see that Hyrdoplane) If you have any, you can send pics to my e-mail: ntadej@hotmail.com

Thanks....sorry to take over some of the thread.

No no, hydroplane, like go on water really fast... Miss Budweiser?? (Not my boat obviously, just an example.)

Oh okay, I thought you were referring to an amphibious UL. I was wondering how you would consider an airplane with a 454ci engine an UL...
