Cam change only, nothing else. Of course a new tune though.

242/242 .610/.610 114 lsa

to a: 248/248 .610/.610 114 lsa

Thanks

Maybe another 10peak hp? Just guessing.

Lumpy

Forgot to ask, how much different will it lope?

Bink

They're both on a 114- I doubt there would be much of a difference in terms of lope.

Lumpy

well how much bigger can I go, with good hp gains but not get too lopey?

How big can that 242/242 number get?

someday

well the bigger u go on duration, the higher it moves ur peak... so u don't want it peaking too high where ur never gonna rev it... do u want a smoother idle? try a 238 on a 116 maybe... or if u want more lope, try a 244 on a 112

Lowering the LSA (the 114 number) will add lope, and so will spliting the duration foward. (the 242 number) Basically, if you went 242/248 on a 112, you would pick up a nice lope. Moving the same cam you have to a 248/248 114 will not change the sound much, if any. It will only move the power further up in the RPM's. No one can tell you how much cam you can stuff in there without knowing the specs of all your stuff.

FireHawk22

look you can go for 112 or if their is 111 and what the thunder racing told me when you go for 111 or 112 you may get more hp.....

I wouldnt bother swapping unless you go alot bigger. Otherwise you wont see much gain for the money spent. I think a 255/255 on 112 with a bit of advance would make a nice power gain but it would lope hard

How streetable would that sucker be? LOL

CHRISPY

1000rpm idle and it'd be perfect

You will move the peak power band to a higher RPM while losing some torque. Your peak HP will likely not change at all just the RPM at which peak is attained. You might consider going to smaller cam to improve performance. Torque rules.

If you are launching the car at 6000rpm at the track, who cares about gaining another 20 ft lbs or torque down low. Go for whatever gives you the most power at 5000+ rpm.

On a 427, I would personally put about a 248/252 and 112 lsa.

Wow that is a BIG cam!

I guess you have some rather large valve reliefs built into your pistons right?

Lumpy

How hard we talkin?

Like daily driving would suck?

Lumpy

It's a street car ONLY, but a daily driver. May see a track once after the cam change. How much HP gain over the 242/242 will I see with the 248/252 112 lsa? Torque gains?

Will it idle like crap, meaning lopey?

Lumpy

I've been told by many that a 242/242 .610/.610 114 lsa is TINY for a 427.

Damn, Last I checked we put big motors in these cars to MAKE them lope hard! I wish I could get more lope out of my X1. IMHO, GO BIG! You'll get used to the shake, rattle and roll!

BTW, the cam your talking about putting in isnt even going to be worth the money for it or the gains you'll see. If you want to see gains you will have to make a significant jump.

If the lope of the cam at idle makes the car feel like the space shuttle blasting off, you have choosen right

I spent the extra $10,000 on my motor for one reason and one reason only, a nice idle. I was going to get a radical H/C car until I found out they shake your fillings out. I know allot of people love that lope, but I ain't one of them, PLUS I like the idea of a 500 RWHP sleeper.

So, what is a significant jump, the 248/252 112 lsa? How will that thing lope?
