engine size autocross
I hope this is in the right place to post I was wondering about what motor I should put in my 69 vette flared 315 squared t56 willwood big brake kit borgeson box t56 6 speed .I know everybody will say ls all the way and I agree but I not want to spend the 16 grand to do it meaning changing all my pulley set up and custom exhaust, this car is primarily used for autocross I was thinking about a blue print 427 or 454 small block the 454 makes 580 hp at 6000 and 570 trq at 4600 not bad for the price with a msd ignition all said and done about 10 grand with a warranty and my second option would be a destroked 406 to a 377 that would have a dart shp block scat crank and rods afr heads and make about 560 hp and 500 trq and rev to 7000 all day long long any thoughts will be appreciated. thanks .
