Hey ya'll,
I'm just a few days away from having my 403 out of my TATA and ready to overhaul. I have decided on keeping the original 403, and don't really want to change my mind. I've read some great builds and talked to a few folks here and there that have helped with a few things, but just want to get an idea of what you guys here think as you've never steered me wrong!
The block appears to be in good shape, and I love the Quadrajets (not to mention, it's a number matched car) so I'd like to keep the Q-Jet also.
To help others who are building a 403, I'll include a list of the parts I've purchased for the build as I start acquiring them. The reasoning for purchasing each individual part can be found throughout many discussions in this thread so if folks are wondering what to use and why, read through these pages!
As far as the build goes, here is a list of the parts I've purchased for the build:
Erson Cam (specs on Page 11)
Full roller lifters
Ga heads (BBO)
ARP Rod Bolts
Rebuild transmission also.
I'm not looking for huge power, I read a build similar to this that put down the numbers I want, which was in the 430hp and 450tq range. Something streetable, fun, and quick.
This seems like the standard for making power out of a 403, up the CR, let it breath better, and add a little more cam to it.
I'm open to all input, except for "ditch the 403 and just build a 400." I'm really wanting to build the 403 and don't want 50 posts saying it's useless.
Thanks for reading guys! This project is coming along slowly but surely.
JJ
