427 build --------------------------------------------------------------------------
I am selling my 348 (555rwhp 549 rwtq 10.5 @ 131 1.50 @ 4500 ft with 6 speed 3620 race weight) and building a 427 this winter. All I have so far is the darton mid blocked w. billet main caps matched to wiseco coated pistons with gfx rings. 11.7:1 static compression ratio with 70 cc heads. Here is the combo I am planning. But I am not in a hury and want to pick the best parts I can for the money. Open for suggestions or changes.
2002 camaro
Ls1 darton mid sleeved block 4.127
Wiseco pistons w. coated skirts and gfx rings. aprox .041 quench 11.7:1 scr
TEA Trick flow cnc 235's
Yella terra ultra lights (non adj)
Vengeance Fast 96 w. 96 TB
Vengeance 247/251 624/624 113 + 3 cam set up at 110 or 111 cl
Morel link bar, Lunati, or New comp cams link bar hyd roller lifters. (What is the best pre load to aim for?)
Manly Billet timing chain. Offered in .005 shorter. Do I need this since my block has been line bored for the billet caps?
Ported and shimed ls6 oil pump.
Hooker 1 7/8 headers
dual 3" with borla xcr's
100mm maf (what brand is best. What about the digital Abaco's)
Fast toys 104mm lid
NGK tr6's
Callies compstar or K1 4" crank
Callies compstar or K1 ultra light rods 6.125"
Mez 55gpm electric water pump.
arp head and main studs
Any difference in pushrod brands?
Switching to a 4L80E with a 3600-3800 stall 1.69 str and 3.73 gears. 28 slick.
This will be stree driven most of the time and raced @ 4500 feet in the 1/8 mile for most of its racing time. Steetability is very important, but I have lived with a g5x3 and a 6 speed for the last 5 years.
Race weight will still be about 3620 and I will still have a nitrous kit in the car but I want to keep it at no more than 125 shot. Shooting for high 9's.
Opinions and suggestions welcome.
