355 TBI buildup...some questions

Hello.

I have to build a 355 SBC from my old 383 SBC. So i have to change the crankshaft, the connecting rods and the pistons. I think, i want to reuse most of the "old" parts.

- 4.030" bored block of course
- AFR 195 (#1040) heads
- 1:1,6 roller rockers and push rods
- Edelbrock Airgap intake manifold with TBI adapter plate
- 454 TBI ported throttlebody with 80´injectors (not sure for reusing, please take a look to my other thread in this forum)
- 4" snorkle homemade air cleaner (bought from a thirdgen-member before a few years)
- Rob´s great EBL
- Zeitronix WBO2
- Flowmaster American thunder exhaust system 3" with high flow cat
- heavy duty oilpump

Followings parts will not be reused:

- Eagle Stroker 383 rotating assembly with harmonic balancer
- 7 qt oilpan ( big pan, terrible y-pipe construction at the moment)
- Stroker 383 valve covers (silly to use them on a 355 cui engine)
- Old headers and ypipe (terrible in cause of the big oilpan)


I ordered the following parts:

- Scat crankshaft
- Badger pistons 4.030"
- New connecting rods 5.7"
- headers and y-pipe from topdown-solutions
- Bearings, piston rings, gasket and other small things...


So, i bought the 383 sbc shortblock before a few years. A friend of me bought the same shortblock for his TransAM. I asked him for cam specifications. They should be:

Mike Jones cam design
280/286 duration; 224/226 @0.05
lift .535 intake; .528 exhaust with 1:1.6 roller rockers
110 degrees lobe centerline.

How do you think about my setup ? Of course, i have to remove the engine from the car and disassembling completely.. So, the big question is, how do you think about the cam specs ?


thank you

Jan

what i dont get is why you are taking out the stroker crank. I mean..... thats a huge horsepower and torque loss.
