How many of your guys are running the 351w main spacers? I am getting close to ordering all my stuff for the 427 big bore motor i want to build but am afraid i will run short financially, alot due to the coast of an aftermarket block. I really didnt want to build a stock 351w block stroker due to the bigger mains and two bolt mains but would save me alot and would most likely get my car running! Are you guys having luck with the spacers and I would imagin a main girdle? It would be a 408 if i go stock block with some TEA 225 or 245 high ports with port matched SV and a tight lash soild roller setup for a ton of street driving and strip and a pro systems carb. Motor will be around 11to1 on pump 93 gas. I have heard the 3" mains dont like the rpm's and spacers seem a little scary but a friend races trucks and ran them in a 351 with a svo 2.75 crank and worked great but low power around 350hp. Just dont want to go another summer watching people driving and racing!
