I am about a year off schedule for building this engine. I am planning to have it ready for spring now. I am building a GM 327cid for my '85 Trans Am. Here is the rundown of what I have so far..
The block (of course) 1967? -- am planning to bore it at least .030
A matching pair of 461X heads -- am planning to have them cut out for larger valves, hardened ex. seats and possibly port matching.
I have a full set of new 2.02 and 1.6 swirl polished valves
Z28 springs
Edelbrock performer rpm intake
Holley 750 carb - (needing rebuild)
Summit 1105 cam (i think) either that or 1106-- have to check
Shorty headers
Speed Pro hardened pushrods
Summit half and half 1.5 and 1.6 aluminum roller rockers. 1.6s going on the exhaust side.
high volume oil pump
MSD Blaster 2 coil
This engine does have the small journal Forged steel crank and was reconditioned and balanced not too long before I got it.
I am aiming to be in the vacinity of 400 hp & torque.
Part of the reason I am building this 327 is because everyone else seems to be builing 350s. That and I have never heard how a 327 sounds. I have been told it's a bit unique due to the short stroke cycle. Besides, a 327 in a Trans Am just seems right to me! lol
I do believe the cam is the 1105. I can't find the card for it. It was bought over a year ago. I got these specs off of the dyno2000 program. Not sure if it is accurate but I guess it's the closest I have right now.
Hydraulic
.050 lift
int lift @ valve .475
ex. lift @ valve .488
IVO -2.0
IVC 46.0
EVO 51.0
EVC 3.0
I might need better springs..might be pushing these to far.
I dunno what I want as far as pistons or distributer.
Any suggestions on those? Or anything else here? Or even not here? lol
I feel like I am missing something. If I figure it out, I'll add it.
This is to be my first engine build and I am on a bit of a budget. Don't think I'm doing too bad so far though.
Anyone have a file for the dyno program to simulate 461Xs? Closest I have is 462.
