Hello, I am freshening up a 98 vortec 5.7 engine , will use a performer vortec intake with an adapter plate, and external EGR plate setup, starting out with a modded stock bore TBI. Need to know if I can use a LT4 cam and maybe use 1.5 rockers to knock some lift off of it to make the idle a little better, The LT4 cam is $80.00 cheaper than the LT1 cam at GMparts. Will be using the 93 GM truck computer system and 4L60E, Hooker 1 5/8 full length with custom Y pipe tig welded by me. From factory-no AIR system. I plan on getting the prom burning set up for this and a Second Gen EFI project but would like to get a cam for this that will run OK to start off with then tune with chip mods. I found that Tunercat does support my PCM. Thanks for any help and suggestions , Dave
Kevin , I said that they do support my PCM and I think it takes 27c512 chips, so i hope there is a flach chip that i can use . have you programmed a 93 PCM? Thanks , Dave
