[TransAm 474]

Good Evening everyone, as many of you are aware of from my other W72 build thread, we are getting ready to build yet another Pontiac 400, this time a 1979 PWH W72 400 out of a Trans Am. The original plan in my other thread was to upgrade the 400 as much as possible while retaining the numbers matching parts on the outside, but after calculating the cost of good pistons, better 5140 rods, and having the crank turned and everything balanced, it comes within a few hundred dollars of just buying the Butler Performance Balanced Stoker rotating assembly ready to install, after I get the block decked and bored, and the end result is much better parts for the money, a bigger 467 c.i. engine, while retaining the numbers matching look to the eye. At this time there will be no head porting in the budget, just a nice rebuild and valve job on the 6x4 heads, upgraded with Ferrea stainless valves, Crower 68404 springs set up at 1.570" Installed Height, and 7/16" studs and poly locks. This engine should come out somewhere between 9.6 to 9.8- 1 compression. We are now thinking we will use the Lunati VooDoo 704 camshaft in this. Here is how the build plan looks now

1979 PWH 400 XX block
Bore- 4.181"
Zero Decked
Butler Performance Rotating Assembly
Eagle 4.250" crank
Eagle 6.800" H-Beam rod

.504"/.527" lift
110° Lobe Seperation
Thinking of Installing it at 104° I.C. according to the advice of Harold Brookshire and Paul Carter
Crower Camsaver lifters
Crower 68404 Valve Spring installed at 1.570"
Cloyes 3512X9 billet timing set
Stock 1.5 rockers
Stock Cast Iron intake
Qjet Recalibrated with Cliff Ruggles parts
Recurved HEI distributor

This is 100% street car on pump gas in an original 1979 Trans Am. What do you'll think about the new stroker plans? I know head porting would be even better for the bigger engine, but it is not in the budget at this time. Sound like a good plan?

Thanks
