Guest Anonymous Posted April 11, 2001 Share Posted April 11, 2001 Hey everyone, I have a few question for you V-8 Z owners. The first question is about the cam selection for my 1995 LT-1 which I am putting into my 280Z. Can anyone recommend a good cam for this engine? Also has anyone used an aftermarket wiring harness and if so, what kind? Any information will help me greatly. Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted April 12, 2001 Share Posted April 12, 2001 what do you want for power/manners? stock cam with 1.6rr's/swapped head gasket/headers etc pumps up nicely all on its own. Next step is a 211/219 LPE cam which is v. well liked on the LT1 or a ZZ4 cam (mix your rockers/1.6 intake/1.52 or so exhaust as LT1 heads are good/ZZ4 ones were/are poor on exhaust hence wider cam split). This has a slight idle lope and great power up to ~425 flywheel, then the HOT CAM is the next/big step IMO (without going huge). It has a definite attitude and I don't recall it's power figures. look at camaroz28.com or other boards full of Lt1's......my dad just got his stock Lt1 running in his 240z and is having trouble putting traction down past 1/3 throttle in lower gears at present (won't slap his new tires on till he's played a bit more ) lots of specs on various roller combos (like your Lt1) at sallee chevrolet's site as well (quick search will find it) ahh, here's some specs rwhp from a dyno day in WA a few friends attended last fall, may be of help/ Ellis either had his 211/219 LPE in or something a hair bigger (not a HOT cam) ________________________ Kurtis Tamez ('97 Z28 automatic (bad/clogged cat)) - 249hp & 272 lb.ft. N/A, 350hp & 424 lb.ft. w/ NOS Joe Waldron ('94 Z28 M6)- Joe's biggest mod I believe is the LT4 Hotcam kit w/ Ed Write Program, 328hp & 327 lb.ft ME ('94 Z28 M6) - All I have is intake/exhaust mods mainly, 281hp 320 lb.ft, I still had the stock y-pipe on w/ hollow cat. conv., now have a Borla y-pipe so maybe that'll change a little Shaun Hoke ('95 Firehawk M6) - Shaun's hp run is stock w/ Hypertech & hollow cat. conv., 287hp & 318 lb.ft. Steve Sampson ('94 Z28 1LE M6) - Steve has mild porting w/ 1.6 roller rockers, springs, uh, I think that's about it for HP mods, Steve? 305hp & 330 lb.ft. And finally ~Ellis~, hmmmm, well you'll just have to ask him what he's got goin' on. I believe it's a cam-job w/ 1.52 RR's(?) and the computer program changes frequently, so you'll have to ask him about that. All I can say is his BEST HP run was at 316, and the best TORQUE run was at 338. ------------------ Of all the things I've lost, I miss my mind the most.

Kevin Shasteen Posted April 12, 2001 Share Posted April 12, 2001 Forgive me for asking...but I assume your swap is going into a "Z"..correct me if I'm wrong. First your have to decide: 1)What your most often driving range (RPM)will be 2)What the weight of the car is 3)What transmission you'll be using 4)What size tires you're using 5)Where you'ld like the Peak-Power to be (RPM-wise) 6)What you'ld like your car to do in the 1/4mile...this is usually a good point of reference for performance Once you've decided what your desired Peak-Power RPM needs are you then can address cam/intake selection & build around that...cam/intakes are usually listed by their Mfg's by their peak-power range(s).

Guest RyalC Posted April 12, 2001 Share Posted April 12, 2001 I'll echo the previous comments on picking a cam - the key is what do you want to do with the car and what are your other parts of the equation (heads ported? how radical? street or race? do you need to pass emissions? where do you want the power - high rpm hp or low-end torque?). However, just to give you something to chew on below is a list of cams (and their specs) used on various LT1 cars.

MYRON Posted April 12, 2001 Share Posted April 12, 2001 I am doing the Lt1 swap as well and have been looking into cams from Street&Performance (http://www.hotrodlane.com) and Tuned Port Specialties (http://www.tpis.com).. both these guys can help you with cam selection computer programming and many other performance mods... Check them out Myron Quote Link to comment Share on other sites More sharing options...
DavyZ Posted April 12, 2001 Share Posted April 12, 2001 RyalC, please tell me you didn't type all those specs out!!! If you did, bless you my son, but you have too much time on your hands!!! Quote Link to comment Share on other sites More sharing options...
Guest RyalC Posted April 12, 2001 Share Posted April 12, 2001 Nope - copy and paste. I believe in "re-use" whenever possible (in other words - I let someone else do all the work) The LT1 and T56 going into my 240Z came from my old '94 Z28. I sold the body to a friend who wrecked his Camaro at Atlanta and I kept the engine and transmission for my conversion. I'm still pretty tight with the f-body gang (specifically the Mid-Atlantic group - some good road racers in the bunch) so I get my technical information from practitioners!
