hi there

would like to know what cam will be the best for my n/a new engine 427lsx with 10.5 cr and trick flow 245 heads + fast intake 92 with throttle
im planing on having nos around 150 hp on nos

drivability is my last concern its a weekend car

any ideas guys ?

Why such low compression? I'd bump it up to at least 11.5:1 maybe closer to 12.1:1 if you can get pure 93 octane and have a good tuner available.

For the cam I'd get a custom grind done. Pat G has always turned out good results. I used Advanced Induction for my old LS1 custom grind and it was great.

Defiantly more CR, you can spray more than that on an LSX motor as well.

Get a custom cam from Pat G. He did the one for my 427ci LS3 and it's awesome.

djfury 5 and the ls1lover - i got the full engine with a really good prise with 200 miles on it thats why i wont change the pistons for now so do u think with n/a tune and a costum cam ill be able to reach around 550rwhp ? and add like 200 shot of nos?

ws66 i would like to try patrick g costum cams

and thanks alot guys

You can for sure make 550rwhp, the combo has to be just right though. 200 shot shouldn't be anything.

550 is easy with a properly built 427.

Contact Brian Tooley! He will set you up with a cam and valvetrain to run reliably and make great power. He also runs a set of TF 245's on his personal combo.

X2 for Brian Tooley he designed the head

255-271-115,LSL lobes , but more comp, 12.0:1 with 30-35 thou quench.., The fast hurts the top end, spreading the lobe centres helps it hold on but you drop cylinder pressure doing so. So increase static compression to compensate.

Im running a 434ci with TFS 245s and the cam im running is a 247/251@112+3

Your compression is pretty low, I would bump it up to 11.5-11.75:1 if you can.

Here is my recommendation...

247/263 .660/.660 @ 1.8 rr 112 LSA 110 ICL or (.624/.624 @ 1.7 rr)

It will have roughly a dynamic compression of 8.35 if you go with a 11.75 static compression, which will keep it 93 pump gas friendly.

Brian Tooley ran a 251/266 .660/.660 @ 1.8 rr 115 LSA in his 454 LS7 build which had a FAST 102 mm and TFS 245cc heads.

If you'd like some advice, give me a call at the shop or shoot me a PM. I've done a lot of TFS H/C/I set-ups, honestly they are fairly easy to cam and a monkey could pretty much do a N/A cam for a cathedral port headed motor.

LilJohn

Yea... well if a monkey can do it... you shouldnt have a problem... lolol.

Geez dude... leave yourself wide open whydontcha.
