400+ CID with 243's? I'm considering buying a 400+ inch short block but I've got a nice set of ported 243's. Has anybody done this and had good results? Its my daily but I still want it to be fast. |
Yes there are a few threads in the dyno section of 418" strokers making 550whp with a quality 243 head and fast intake. |
Yep, I believe it can be done successfully. It may not be 100% optimal for an all out NA engine but should be a very nice driver. |
If it's truly your "daily driver" I'd by a beater first lol |
The TEA Stage 3s made 600rwhp back in 2005 on a 440. They are lousy heads, obviously. |
Ported nicely and big enough valve they can be made to flow 330+ cfm which is going to be pretty good even for a 402 size stroker. Velocity might suffer down low, but with a stroker and decent compression you'll make plenty of torque down low to make up for that. |

I never knew TEA had a stg III 243s. What does this consist of? |
Think they just have bigger valves, 2.08 and 1.60. The porting is usually the same. |
I'm running texas speed 243s w bigger valves on a 402, 11.5 comp, fast 102, 235/242 111 and it made 537 to tires. |
I'm running ai 243 heads on my 418. They perform very well imo. Sure I could of put some really nice afr 245's or even a set of ls3 heads on it. I had these heads already and had to stop somewhere! |

Yeah, its really my daily. I've got a truck though. That's what I needed to know guys. Thanks a lot for the feedback! |
