Ok I am starting to plan out my engine project for the spring. I am wanting to build a 383 stroker for my blazer. This is my DD so nothing wild and I want to have good gas mileage with good performance like everyone else. At first i was going to do big block but that is out because of cost and gas mileage. So far here what im looking to run Eagle 3.750 stroke Pro Speed flat top pistons .30 over New Balance and Flex plate I'm going to run Vortec Heads but Depending on how much money i have it will either be Sumit Racing Vortec Heads or GM Perfomance Parts Im looking to run between a 9-1 to a 9.5-1 compression Keeping the Quad on maybe get it rebuilt. Have plans in the future for TBI but not anytime soon. Here is what i need help on 1. I have been told that some year blocks are stronger than other. I know I want a 4 bolt, but are there an years i should look for. 2. I dont know what Cam i want to run yet. I want either a 260, 268 or 270. But dont know which one yet or what brand. i want my torque band to be between 2400 and 3000. 3. Last is the ignition. Right now it mainly stock, just up graded wires(Accel 300+) and an upgraded HEI head just a little better than stock. Will that be fine or will i need to upgraded and what would be a good cheap upgrade? Now I'm a colloge student so funds are short so any info. would be helpful.
